How to fix "Unable to install printer" 0x000003eb error in Windows?

Error 0x000003eb appears when Windows cannot finish installing a printer driver, either in the Add Printer wizard or when you connect to a shared printer. The code only says "cannot complete this function", and in most reports the reason is an old or half-installed driver package. Remove the printer together with its driver package first, then install the manufacturer's current driver.

Facts checked on 14 October 2026. Steps written for Windows 11 (25H2 and 26H2) and Windows 10 22H2.

What "Operation could not be completed (error 0x000003eb)" means

0x000003eb is a hexadecimal number. In decimal it is 1003, and Microsoft's list of system error codes names it ERROR_CAN_NOT_COMPLETE with the text "Cannot complete this function." It is one of the least specific errors Windows has. The Print Spooler started a job, here the installation of a driver, hit a problem on the way and gave up.

So the code does not name the cause. What it does tell you is where the trouble is: in the driver, not in the cable, the ink or the network address. The printer itself is usually fine.

Why Windows is unable to install the printer: causes of 0x000003eb, ranked

Microsoft gives no cause for this code in the printing context. The ranking below is built from what the code means, from Microsoft's documents about how printer drivers are stored and installed, from one manufacturer's bulletin and from what administrators report. It runs from the common to the rare.

The reader's case at the top of this page fits cause 1 and cause 5 at once: a printer of one maker was replaced by a printer of another, and the old software was still installed. Removing the old printer's driver package and its programs before the new setup covers both.

Where a printer driver lives in Windows: Type 3 and Type 4 drivers

Removing a printer in Settings does not remove its driver. A printer driver sits in up to four places, and a leftover in any of them can make the next installation stop with 0x000003eb. Knowing the four places is what separates a real repair from trying the setup program again and again.

The Type column on the Drivers tab matters. A Type 3 driver is the classic kind: its files are copied into the spooler's folder, where they can collide with files of another driver. Microsoft describes the newer Type 4 model as one that is run directly from the Driver Store, which in its words removes the possibility of file collisions.

• Type 3 leftovers can sit in the registry, in the 3 folder and in the Driver Store. Fix 1 cleans all three when it works. Fix 4 is for the case when it does not.
• Type 4 leftovers are the package in the Driver Store and its entry. Renaming the 3 folder does nothing for them. Use Fix 1 or Fix 3.
• Print processors are small Windows components that turn a spooled job into data for the printer. Each driver names the one it uses. If a driver points to a print processor that is gone, Windows cannot start that printer. Microsoft's answer is to remove the driver package and install a new driver.

Error 0x000003eb on Windows 11 and Windows 10: the driver rules since 2021

The error is the same on both systems and the fixes are the same, but the rules around printer drivers are not what they were when most forum answers were written. Four dates explain why an installation that once worked can fail now.

Windows 10 22H2 has the 2021 change and the class driver, and Microsoft says the end of servicing plan does not apply to it. Its support ended on 14 October 2025, so it receives no further fixes for the print components. Where a path differs between the two systems, the steps below give both.

How to fix error 0x000003eb: eight fixes in order

Fix 1 to Fix 3 clean out the old driver and put a current one in its place, and they solve most cases. Fix 4 resets the spooler's driver records, Fix 5 is for shared printers, Fix 6 avoids the maker's driver. Fix 7 and Fix 8 are the general checks.

Fix 1. Remove the printer together with its driver package

5 to 10 minutesLow riskFor everyone who sees "Unable to install printer". It needs an administrator account.

A new installation does not start from zero: Windows finds the driver that is already registered for the model and tries to reuse or update it. When that copy is damaged or incomplete, the function cannot finish. Removing the driver entry and its package forces a clean copy. An independent Windows knowledge base gives this cure for the code: remove the printers, then delete their drivers.

1. Open Settings > Bluetooth & devices > Printers & scanners. On Windows 10 it is Settings > Devices > Printers & scanners.
2. Select the printer that fails, if it is listed, and select Remove. Do the same for other printers of the same maker that you no longer use.
3. Press Win + R, type printui /s /t2 and press Enter. The print server properties of your own PC open on the Drivers tab.
4. If the buttons are greyed out, close the box, open Command Prompt as administrator and run the same command there.
5. Select the driver that belongs to the printer model and select Remove.
6. Choose Remove driver and driver package, then select OK and confirm.
7. If Windows answers that the driver is in use, restart the Print Spooler service and repeat steps 5 and 6 at once.
8. Restart the PC, then install the printer again with Fix 2.

The same box by the command Microsoft documents

rundll32 printui.dll,PrintUIEntry /s /t2

Microsoft documents /s as the switch that shows the properties of a print server and /t as the number of the page to open, counted from zero. Page 2 is the Drivers tab. The list shows each driver with its processor and its type. A printer of one maker often has two entries, for example a PCL and a PostScript driver: remove both.

Where the Services window is and what each command in it does: Check and restart Windows services

Fix 2. Install the manufacturer's current driver for your Windows version, as administrator

10 to 15 minutesNo riskAfter Fix 1, or when the driver comes from a disc, an old download or a setup program that stops.

The error belongs to the driver you feed to Windows as much as to what is already there. Microsoft's own advice for driver trouble is a package from the maker's site that matches your Windows version and system type, and it warns that the software on a printer's disc might be outdated.

1. Open Settings > System > About and read System type: 64-bit, or ARM based processor.
2. Go to the support site of the printer's manufacturer and search for the exact model. The model number is printed on the printer.
3. Download the newest driver or software package that names your Windows version and your system type.
4. Sign in with an administrator account, or right-click the downloaded file and select Run as administrator.
5. Follow the setup program. Connect the printer only when the program asks for it.
6. If the setup program fails, open Printers & scanners, select Add device, then Add manually.
7. Choose Add a local printer or network printer with manual settings, select the port, then Have Disk and open the folder with the unpacked driver.
8. If Windows asks which version of the driver to use, select Replace the current driver.
9. Select Print a test page, then Finish.

• One printer, several drivers. Makers often offer a universal driver and a model-specific one, or a PCL and a PostScript version. Xerox's bulletin on this code says the model-specific driver installs where its universal driver fails. If one kind stops with 0x000003eb, try the other.
• Avoid drivers for older Windows. Microsoft's tip is to stay away from drivers marked for older or unsupported Windows versions unless nothing newer exists.
• A 32-bit driver does not install on 64-bit Windows. Windows 11 exists only in 64-bit form.

The earlier version of this guide installed the driver through Device Manager: Update driver, Browse my computer for drivers, then Let me pick from a list of available drivers on my computer. Microsoft still lists Device Manager as one way to install a printer driver. All the driver commands of Device Manager: Update, roll back or reinstall a driver.

Fix 3. Delete the leftover package from the Driver Store with pnputil

10 minutesLow riskFix 1 could not remove the driver, or the code returns although the Drivers tab is clean. Needs an administrator.

Windows installs every driver from the Driver Store, and a package can stay there after its printer and its entry are gone. The next installation of the same model then picks up the old package again. PnPUtil is the tool Microsoft ships for listing and deleting packages in the store.

1. Right-click Start and select Terminal (Admin). On Windows 10, open Command Prompt as administrator.
2. Run the first command below. It lists the printer driver packages that did not come with Windows.
3. Find the block whose provider is the maker of your printer and write down its published name, a file such as oem12.inf.
4. Run the second command with that name. It saves a copy of the package, which is your undo.
5. Run the third command with the same name. /uninstall also takes the package off any device that still uses it.
6. Restart the PC and install the printer again with Fix 2.

Commands, one per line. Replace oem12.inf with the name from your list.

pnputil /enum-drivers /class Printer
md C:\DriverBackup
pnputil /export-driver oem12.inf C:\DriverBackup
pnputil /delete-driver oem12.inf /uninstall

Fix 4. Reset the spooler's driver records in the registry and in the drivers folder

20 to 40 minutesRead the warningEvery printer model fails, or a driver stays on the Drivers tab and cannot be removed. Needs an administrator.

The spooler keeps one registry key for each Type 3 driver and the driver's files in its 3 folder. When the two no longer match, the tools of Fix 1 fail and so does every new installation. An administrator describes this state on his blog for the same code: the registry entries were there, the files were not. Clearing both lets the spooler build clean records.

1. Remove the printers that fail under Printers & scanners, as in Fix 1.
2. Open Command Prompt as administrator and run net stop spooler.
3. In the same window, run the export command shown below these steps. It writes the backup file to your desktop.
4. Press Win + R, type regedit and select OK. Go to the key shown below these steps.
5. Under Version-3, right-click the key with the name of the driver that fails and select Delete.
6. Close Registry Editor, run net start spooler and try the installation again with Fix 2.

Step 3: back up the whole Print key

reg export "HKLM\SYSTEM\CurrentControlSet\Control\Print" "%USERPROFILE%\Desktop\print-backup.reg"

Step 4: the Type 3 drivers of 64-bit Windows

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows x64\Drivers\Version-3

That was the small step: one driver. If the code is still there, do the full reset that administrators report for this error. It is the method of the earlier version of this guide, with the folder corrected for 64-bit Windows.

1. Run net stop spooler again in the administrator Command Prompt.
2. In Registry Editor, delete the remaining keys of printer makers under Version-3. Leave Version-4 and Print Processors as they are.
3. Open File Explorer at C:\Windows\System32\spool\drivers\x64.
4. Rename the folder 3 to 3.old. Do not delete it.
5. Run net start spooler.
6. Install your printers again with Fix 2, the failing one first.

• Undo. Stop the spooler, delete the new 3 folder if Windows made one, rename 3.old back to 3, double-click print-backup.reg and start the spooler.
• 32-bit Windows 10. The key is Environments\Windows NT x86\Drivers\Version-3 and the folder is spool\drivers\W32X86\3. The earlier version of this guide gave this folder for every PC, which is wrong on 64-bit Windows.
• Where the paths come from. Microsoft's KB5005652 names the folder spool\drivers\x64\3. The registry path is the one administrators give and the one our own screenshot shows. We found no Microsoft page that describes this reset, and we could not confirm the folder name on ARM PCs.
• Microsoft's own keys. Entries with Microsoft in the name belong to Windows. We could not confirm that Windows creates them again by itself, so the export from step 3 is what brings them back.

Fix 5. Shared printer: install the driver with administrator rights

10 to 15 minutesLow riskThe message is "Windows cannot connect to the printer. Operation failed with error 0x000003eb". Needs an administrator once.

A shared printer gives its driver to your PC when you connect, which Microsoft calls Point and Print. Windows updates released on 10 August 2021 and later require administrative privilege for that by default, to address the vulnerability CVE-2021-34481. A standard user is stopped in the middle of the driver installation.

1. Sign in to your PC with an administrator account and install the driver for the printer model first, with Fix 2. Where you can, use the same driver version as the computer that shares the printer.
2. Sign in as the everyday user and add the shared printer again by its path, \\ComputerName\PrinterShareName.
3. If Windows asks for credentials or asks whether you trust the printer, enter an administrator user name and password.
4. If an administrator gets the code too, remove the driver of this model from your PC with Fix 1 and connect again, so that a clean copy is fetched.
5. If it still fails for an administrator, check the policy Only use Package Point and Print under Computer Configuration > Administrative Templates > Printers. Microsoft says it must be disabled when drivers cannot be installed even with administrator privilege.
6. Try the same printer from a second PC. If every PC fails, the driver on the sharing computer is damaged: do Fix 1 and Fix 2 there.

Opening the editor and what to do on Windows Home: Open the Local Group Policy Editor. If the shared printer cannot be reached at all, or the code on screen changes, our guide to printer error 0x00000006 covers the network, sign-in and RPC side of shared printers.

Fix 6. Let Windows use its own driver instead of the manufacturer's

5 to 10 minutesNo riskA printer from recent years, an ARM PC, or a maker's driver that will not install whatever you do.

From Windows 10 21H2 on, Windows supports Mopria compliant printers over network and USB with its own IPP class driver. Microsoft says this removes the need for the maker's installers and drivers. When no third-party driver is installed, there is no third-party package that can fail.

1. Remove the printer and the maker's driver as in Fix 1, so that Windows does not reach for the broken package again.
2. Switch the printer on and connect it to the PC or to the same network as the PC.
3. Open Settings > Bluetooth & devices > Printers & scanners and select Add device. Windows 10: Add a printer or scanner.
4. When your printer appears in the list, select Add device next to it.
5. If it is not found, select Add manually, choose the manual settings option, select the port, and on the driver page select Windows Update.
6. Wait while Windows loads the list, then select the manufacturer on the left and the model on the right.
7. Print a test page.

• The switch. It is under Printer Preferences on the Printers & scanners page. Microsoft's path to switch it off is Turn Off, then Yes, after which printers that are not compatible can be installed.
• Think before you switch it off. Microsoft highly recommends the mode for its security benefits. If your printer works with the Windows driver, leave the mode on and do without the maker's driver.
• What you may lose with the Windows driver. Extras of the maker's software. For a multi-function device, Microsoft says printing and fax work over IPP, and scanning works over WS-Scan or eSCL.
• Very new models. Since 15 January 2026, Microsoft publishes no new printer drivers to Windows Update for Windows 11. A missing model in the list is expected: the class driver or the maker's package are the two routes left.

Fix 7. Install the printer in a clean boot, after removing the old printer's software

15 to 20 minutesLow riskYou replaced a printer of another brand, or the setup works on one day and not on another.

Printer software leaves services and status monitors running, and they hold on to spooler files while a new driver is being copied. A clean boot starts Windows without programs from other companies. The accepted answer in a Microsoft Q&A thread about this code suggests the same step.

1. Open Settings > Apps > Installed apps and uninstall the software of the printer you no longer own: the driver suite, the scan tool, the status monitor.
2. Restart the PC.

Removing a program completely, including the Control Panel route that old printer suites need: Uninstall a program or app in Windows. Then start Windows in a clean boot:

1. Open System Configuration. Select Search on the taskbar, type msconfig and select System Configuration from the results.
2. Hide Microsoft services. On the Services tab, select the Hide all Microsoft services check box. Only services from other companies stay in the list.
3. Disable the remaining services. Select Disable all, then select Apply.
4. Open Task Manager. On the Startup tab of System Configuration, select Open Task Manager.
5. Disable the startup apps. On the Startup apps tab in Task Manager, select each item whose status is Enabled and select Disable. Write down or take a screenshot of the items you disable: you need the list to turn them back on.
6. Confirm the changes. Close Task Manager. On the Startup tab of System Configuration, select OK.
7. Restart and test. Restart the PC. Windows now starts in a clean boot environment: try again the thing that failed (run the app, install the update, uninstall the program).

These steps were written for Windows 11 25H2 and 26H2. The full page with the other versions and what each result means: How to perform a clean boot in Windows

• In the clean boot, run the installation from Fix 2 once more.
• Afterwards, switch everything back on. Open System Configuration again, select Enable all on the Services tab, enable the startup apps and restart. A PC left in a clean boot runs without its security and backup programs.
• A correction to the earlier version of this guide. It also ticked Safe boot on the Boot tab. That is Safe Mode, not a clean boot, and it is no help when you want to install a driver. Leave that box empty.

Fix 8. Repair the Windows system files and install pending updates

20 to 40 minutesNo riskNothing above helped, the Print Spooler stops by itself, or Windows shows other faults too.

The spooler, the Add Printer wizard and the built-in print components are Windows files. If one of them is damaged, every driver installation can stop with the same general code whatever driver you choose. The system file check compares them with clean copies, and Xerox's bulletin shows that a Windows update has cured this code before.

1. Open an elevated command window. Right-click Start and select Terminal (Admin), or type cmd in the search box, right-click Command Prompt and select Run as administrator. Select Yes when Windows asks for permission.
2. Run DISM first. Type the command below and press Enter. DISM downloads clean copies of damaged components from Windows Update, so it can take several minutes. Wait until it says The operation completed successfully.

   DISM.exe /Online /Cleanup-Image /RestoreHealth

3. Run System File Checker. In the same window, type the command below and press Enter. Do not close the window until the verification reaches 100%.

   sfc /scannow

4. Read the result and restart. Compare the last message with the table below this guide, then restart the PC so that repaired files are loaded.

These steps were written for Windows 11 24H2 and 25H2. The full page with the other versions and what each result means: Run DISM and SFC to repair Windows system files

1. Open Settings > Windows Update and select Check for updates. On Windows 10 it is Settings > Update & Security > Windows Update.
2. Install everything that is offered, including the driver updates under Advanced options > Optional updates.
3. Restart the PC and install the printer again with Fix 2.

If the error is still there: the logs to read and what to send to support

The message box shows only the code. Two logs record what the spooler and the driver installation were doing when the function stopped, and three tests tell you which side to work on.

1. Type event viewer in the search box on the taskbar and open Event Viewer.
2. Open Applications and Services Logs > Microsoft > Windows > PrintService and select Admin. Look for errors at the time of your last attempt.
3. Right-click Operational and select Enable Log, try the installation once more and read the new entries. Switch the log off again afterwards.
4. Open %SystemRoot%\inf\setupapi.dev.log in Notepad and go to the end. Microsoft says each section of this log records one device or driver installation.

• What to send to the manufacturer's support: the exact message, the printer model, the file name and version of the driver package, your Windows version and system type, the PrintService events and the last section of setupapi.dev.log.
• When it is not a fault you can repair: the maker offers no driver for your Windows version, the PC is an ARM PC and the maker has no ARM64 driver, or Windows protected print mode is enforced by your organisation. In all three cases, Fix 6 is the route that remains.
• It is not the printer's hardware. The error appears before a single page is sent. A printer with a hardware fault installs normally and fails later with other messages.

How to undo the changes made on this page

Fix 2, Fix 6 and Fix 8 leave nothing to undo. For the others, the table shows the way back. Keep the two backups from Fix 3 and Fix 4 until every printer has worked for a few days.

How to keep error 0x000003eb from coming back

One habit prevents most repeats: treat the driver as something that has to be uninstalled, like a program. A printer that is only removed from the Settings list leaves its driver behind for the next one to trip over.

Frequently asked questions

What does error 0x000003eb mean?

It is Windows system error 1003, ERROR_CAN_NOT_COMPLETE, and Microsoft's text for it is "Cannot complete this function." With a printer it means that the Print Spooler began to install a driver and could not finish. The code says nothing about the reason. In the reports we read, the usual reason is an older or half-installed driver package of the same maker, followed by an outdated installer and by missing administrator rights.

Is 0x00003eb the same error as 0x000003eb?

Yes. 0x00003eb, 0x0000003eb, 0x000003eb and 0x3EB are one number written with more or fewer zeros in front, and Windows itself always shows eight digits after 0x. All of them are error 1003. Do not mix it up with 0x000003e3, which has a different third digit from the end and belongs to a different problem with shared printers, or with 0x00000003.

Why do I get "Windows cannot connect to the printer. Operation failed with error 0x000003eb" on a shared printer?

Because connecting to a shared printer installs its driver on your PC, and that installation is what fails. Since the Windows updates of 10 August 2021, a driver that comes from another computer needs administrator rights, so a standard user is stopped. The second common reason is an older driver of the same model on your PC. Install the driver as an administrator first, then connect again. Fix 5 has the steps.

Is it safe to delete the keys under Version-3 and rename the 3 folder?

It is a known repair, but it is not harmless, which is why it is Fix 4 and not Fix 1. It removes every Type 3 printer driver from the PC, so all printers that use one must be installed again. Microsoft's rule for such work is to export the whole Print key first and to stop the spooler while you change anything. With the export and the renamed folder kept, the reset can be undone completely.

What is the difference between a Type 3 and a Type 4 printer driver?

A Type 3 driver is the older model: its files are copied into the spooler's folder, spool\drivers\x64\3 on 64-bit Windows. A Type 4 driver arrived with Windows 8. Microsoft says it is run directly from the Driver Store, which removes the possibility of file collisions. For this error it decides where leftovers sit. The folder reset of Fix 4 only helps Type 3 drivers, while pnputil in Fix 3 works for both.

Does error 0x000003eb appear on Windows 11 as well as Windows 10?

Yes, on both, and the fixes are the same. Two things differ. Windows 11 has Windows protected print mode, which refuses third-party drivers while it is on. Microsoft is also retiring third-party printer drivers on Windows 11 in stages: no new ones on Windows Update since 15 January 2026, and its own class driver preferred since 1 July 2026. Windows 10 is outside that plan, but it has been out of support since 14 October 2025.

Can I fix 0x000003eb without an administrator password?

Only in part. Installing and removing printer drivers needs administrator rights, and so do pnputil, the registry and the spooler service. A standard user can add the printer with Add device and hope that Windows already has a suitable driver, as in Fix 6. You can also collect the facts for the administrator: the exact message, the printer model and the time of the attempt. On a work PC, do not try to get around the limit.

Should I turn off the antivirus to install the printer?

No, not as a fix. Microsoft's printing guidance does note that security programs which scan the spooler folders can cause side effects such as access denied errors. The clean answer is the clean boot of Fix 7, which starts Windows once without programs from other companies and is undone with a restart. If the printer installs there, add exclusions for the spool files (.SHD and .SPL) in the security program, as Microsoft's guidance does, and leave protection on.
