How to fix Microsoft Office error 30068-39 in Windows?

Error code 30068-39 means Office setup could not get the Microsoft Office Click-to-Run Service to run, most often after an earlier Office was removed or half removed. Restart Windows normally and run setup again. If the code comes back, make sure the service is not disabled, then remove every Office with Microsoft's uninstall troubleshooter.

Facts checked on 15 October 2026. Steps written for Click-to-Run versions of Microsoft 365, Office 2016 to 2024 on Windows 11 (25H2 and 26H2) and Windows 10 22H2, read against Microsoft's support page for error 30068.

What error code 30068-39 means in Microsoft Office

Every desktop Office from Office 2016 to Microsoft 365 is installed by Click-to-Run. The setup window you open hands the real work to a Windows service called Microsoft Office Click-to-Run Service. When setup cannot get that service to start or answer, it stops and shows a code that begins with 30068. The 39 after the dash is a step inside setup that Microsoft does not explain.

In English the window reads Something went wrong with Error Code: 30068-39 and a number in brackets. In the Danish example above the heading means a system restart is needed and the text says to restart the computer and try again. The code is never translated, so a Russian reader searching код ошибки 30068 39 sees the same digits.

What causes Office error 30068-39, from the most common to the rare

Microsoft lists its solutions for 30068 with the most common first: a restart, the service, then uninstall and reinstall. The ranking below follows that order and what users report in the 30068-39 threads on Microsoft Q&A. It is an order of likelihood, not a statistic.

How to fix error code 30068-39 when you install Office

Fix 1 to Fix 3 are Microsoft's own three solutions for 30068, in Microsoft's order. Fix 4 finishes a removal the troubleshooter could not complete. Fix 5 to Fix 7 are for the rarer causes, from the cheapest to the slowest.

Fix 1. Restart Windows normally and run Office setup again

5 minutesLow riskEveryone first. Above all when you removed or updated Office and have not restarted since.

Microsoft lists a restart and a new installation as the most common solution for 30068. An uninstall can leave the old service waiting for a restart, and the setup window itself often asks for one.

1. Select Close in the setup window.
2. Save your work and select Start > Power > Restart. Use Restart, not Shut down.
3. Sign in to Windows with an administrator account.
4. Sign in at microsoft365.com with the account that owns Office, or open Microsoft's page for Office 2021, 2019 or 2016 if you bought a one-time version.
5. Download a fresh installer from there and run it. Do not reuse an old installer file.

Fix 2. Check that Microsoft Office Click-to-Run Service is not disabled

5 minutesLow riskFix 1 did not help, the code ends in (1058), or someone tuned the services on this PC.

This is Microsoft's second solution for 30068. Setup cannot install anything while the service it hands the work to is set to Disabled. Turning it back to Manual or Automatic lets setup start it.

1. Press Win + R, type services.msc and select OK.
2. Scroll to Microsoft Office Click-to-Run Service.
3. Look at the Startup Type column. If it says Disabled, right-click the service and select Properties.
4. On the General tab, set Startup type to Manual or Automatic, then select Apply and OK.
5. Run Office setup again as in Fix 1.

All the screens of services.msc: Check and restart Windows services.

Fix 3. Remove every Office with Microsoft's uninstall troubleshooter, then install again

20 to 45 minutesRead the warningFix 2 did not help, you removed an older Office before, or the code ends in (2) or (3).

Microsoft's third solution for 30068. When an Office is half removed, setup finds its traces and calls a service or a folder that no longer works. The troubleshooter clears every Click-to-Run version, so the next installation starts from nothing.

1. Sign in to Windows with an administrator account.
2. Open Microsoft's uninstall troubleshooter link.
3. Select Open when the browser says This site is trying to open Get Help.
4. Follow the prompts and restart the computer when you are asked.
5. Install Office again from microsoft365.com, or with Microsoft's steps for Office 2021, 2019 or 2016.

Fix 4. Remove Office leftovers by hand when the troubleshooter misses them

30 to 45 minutesRead the warningThe troubleshooter found nothing or failed, you had Office 2024, or the Click-to-Run service is missing.

Microsoft's tip for a troubleshooter that does not remove everything is to uninstall Office by hand. One administrator with 30068-39 reported that the troubleshooter found no Office files, while setup still failed: what is left is in the folders, tasks and keys the manual steps cover.

1. Open Settings > Apps > Installed apps (Windows 10: Apps > Apps & features) and remove every entry that starts with Microsoft 365, Microsoft Office or Office, language packs too. All steps: Uninstall a program or app in Windows.
2. Restart the PC.
3. Open Microsoft's page Manually uninstall Office and choose the Click-to-Run steps.
4. Follow them for the folders, scheduled tasks and registry keys in the order Microsoft gives. Do not delete the service on its own first.
5. Restart the PC and install Office again as in Fix 1.

Fix 5. Turn off Safe boot and return to a normal startup

5 minutesLow riskThe code ends in (1084), Windows shows Safe Mode in the corners, or you followed a clean boot guide that ticked Safe boot.

In Windows' list of error codes, 1084 means a service cannot be started in Safe Mode. Some older guides for this error, our own earlier version among them, told readers to tick Safe boot during a clean boot, which leaves Windows in Safe Mode where Click-to-Run cannot run.

1. Press Win + R, type msconfig and press Enter.
2. On the Boot tab, clear the Safe boot check box.
3. On the General tab, select Normal startup. This also turns back on the services and startup items a clean boot switched off.
4. Select Apply and OK, then Restart.
5. Run Office setup again.

Fix 6. Pause a third-party antivirus for one installation

10 minutesLow riskYou use a security app other than Microsoft Defender, and Fix 1 to Fix 5 did not help.

A security app that blocks a new service or its files can stop Click-to-Run before it starts. One paused run shows whether the app is the cause. Microsoft does not name antivirus on its 30068 page, so this comes late.

1. Download the Office installer while protection is still on.
2. Pause the security app for the shortest time it offers: Turn off Microsoft Defender protection for a moment.
3. Run the Office installer.
4. Turn protection back on right after setup ends.

If setup works only while the app is paused, add the Office installer and Click-to-Run to its exceptions or ask its maker. The fix belongs in the security app, not in leaving it off.

Fix 7. Update Windows and repair system files, then install Office again

20 minutes to 1 hourLow riskEvery fix above failed, or other programs also fail to install.

Microsoft does not tie 30068-39 to Windows itself. When every Office-specific fix fails and other installers fail as well, damaged Windows files can stop a new service from registering, so the last step is to repair Windows.

1. Open Start > Settings > Windows Update, select Check for updates, install what is offered and restart.
2. Run the system file check and DISM once: Run DISM and SFC to repair Windows system files.
3. Restart the PC and run Office setup again.

If error 30068-39 is still there: what to check and what to send

The setup window shows only the code. Click-to-Run setup writes text logs to the %temp% folder of the user who ran it, and Windows records service failures in Event Viewer. We could not confirm from Microsoft which log line belongs to 30068-39, so read them as a hint.

1. Run setup once more and note the time.
2. Press Win + R, type %temp% and press Enter. Sort by Date modified, newest first.
3. Open the newest .log files and search with Ctrl + F for 30068, then for error.
4. Press Win + R, type eventvwr.msc and look under Windows Logs > System for a service error about Click-to-Run at that time.

• Volume licence and the Office Deployment Tool. An administrator reported 30068-39, then error 0-2031, when installing Office 2019 with a volume licence. Microsoft's consumer support could not help, so a business or volume licence case goes to your organisation's admin or Microsoft's business support.
• A licence problem shows a different message. Activation errors and Unlicensed Product appear after Office opens, not during setup. Check that your Office shows at account.microsoft.com.
• What to send to Microsoft support: the full code with the number in brackets, the Office product and year, and the Startup type of the Click-to-Run service. Add what you removed before, the Windows version from Settings > System > About and the newest setup log.

How to avoid error 30068-39 the next time you install Office

Most 30068-39 cases start with an old Office removed halfway, a skipped restart or a service someone switched off. A few habits avoid nearly all of them.

Frequently asked questions

What does error code 30068-39 mean?

It means Office Click-to-Run setup could not get its Windows service, Microsoft Office Click-to-Run Service, to start or answer. The window says Something went wrong and shows Error Code: 30068-39 with a number in brackets. Microsoft has one support page for every error that contains 30068, and its fixes in order are a restart, the service check and a full uninstall and reinstall. Microsoft does not explain the 39 itself.

What does 30068-39 (2) mean?

The 2 in brackets looks like the Windows code for a file that cannot be found. Microsoft does not confirm this for Office. In the Microsoft Q&A thread on 30068-39 (2), the reader saw it after removing Office completely, and the Click-to-Run service could not even show its description. That points to a half-removed Office, so start with the uninstall troubleshooter (Fix 3) and the manual cleanup (Fix 4).

Why do I get error 30068-39 after I removed Office?

Because the removal was not complete or Windows has not restarted since. Setup finds traces of the old Office, such as its service, folders or registry keys, and tries to use them. Restart normally first (Fix 1). If that does not help, run Microsoft's uninstall troubleshooter, which clears every Click-to-Run version, then restart and install again (Fix 3). Use the manual steps (Fix 4) if the troubleshooter finds nothing.

Are 30068-47 and 30068-44 different from 30068-39?

They belong to the same 30068 family, and Microsoft's support page applies to every error that contains 30068. The second number changes and is not explained by Microsoft. The fixes on this page work for 30068-47 too. For 30068-44, the bracket number 1715 is common, and we cover it in our guide to Office error 30068-44.

Can I install Office in Safe Mode to avoid conflicts?

No. Office setup needs Microsoft Office Click-to-Run Service, and Windows does not start that service in Safe Mode. The bracket number 1084 means exactly that kind of refusal. If you want to rule out other programs, use a clean boot, which turns off only third-party services and startup apps. Then return to Normal startup in System Configuration as soon as the test is over (Fix 5).

Will fixing 30068-39 delete my documents or emails?

No. The error stops setup and touches no files, and uninstalling Office removes the apps, not the documents you made with them. The manual cleanup (Fix 4) removes Office settings and cached sign-ins, so copy any Outlook .pst file first. Mail in Microsoft 365, Outlook.com or Gmail stays on the server and comes back when you sign in again.

I have Office 2016. Can I still install it?

Yes, if you have its product key or it is linked to your Microsoft account, and the fixes on this page are the same. Office 2016 left support on 14 October 2025, so it gets no more security updates. Microsoft's uninstall troubleshooter still removes Office 2016, and its download page still lists it. If you have a Microsoft 365 subscription, install that instead.

Does the old Support and Recovery Assistant still fix 30068-39?

No. Older guides, our own earlier version among them, sent readers to the Microsoft Support and Recovery Assistant and the file SetupProd_OffScrub.exe. Today the uninstall link on Microsoft's 30068 page opens the Get Help app, which removes Microsoft 365, Office 2021, Office 2019 and Office 2016. It needs Windows 10 or higher and cannot remove Office 2024 yet.

What are ai30068, код ошибки 30068 39 and other spellings?

Код ошибки 30068 39 is Russian for error code 30068-39, the same Office setup error, and every fix here applies unchanged. We found no Microsoft code called ai30068. If you meant the Office setup code 30068, this page covers that family. A plain 30068 search also lands here, since Microsoft treats every 30068 code with the same three fixes. Microsoft's support pages are available in Russian if you prefer.

What causes error 30068-39 in the first place?

Most often a restart is pending after an Office was removed or updated. Next come a disabled Click-to-Run service and a half-removed old Office whose traces confuse setup. Rarer causes are Windows stuck in Safe boot after a clean boot test, a security app that blocks the service, and damaged Windows files. The table near the top ties each cause to its fix.
