How to fix Microsoft Office error 30180-4 in Windows?

Error code 30180-4 means Office setup could not finish downloading Office, because the connection, a proxy, a firewall or antivirus software got in the way. Microsoft's first fix is the Office offline installer, which downloads the whole package as one file. If that fails too, use a cable or another network and turn off the proxy and VPN for one installation.

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

What error code 30180-4 means when installing Office

The normal Office installer is small. It does not hold Office itself: it downloads the apps from Microsoft while it installs them, a method Microsoft calls Click-to-Run. Error 30180-4 is what setup shows when that download breaks off or never starts.

• 30180 is the first part of the code. Microsoft's page for it lists only network and security causes, nothing about the licence or the account.
• 4 is the second part. Users report other codes that end in -4, such as 30174-4 or 30125-4, with the same message about the internet connection.
• Your internet can look fine. Web pages may load while setup still fails, because a proxy, a firewall or a security app can block only the Office download servers.

Microsoft's page for this code says you might see it if your antivirus software, firewall, proxy settings or connection prevent you from installing Office. It lists the most common solution first, the offline installer, and this guide follows that order.

Why Office setup stops with error 30180-4

The causes below come from Microsoft's page for 30180-4, ranked by Microsoft's own order of solutions. The last row is the case of the reader above: a Windows reset can bring back an Office that the PC maker installed.

Error 30180-4 is not a licence or account error. If the download works but Office later says it is not activated, that is a different problem with its own codes.

How to fix error code 30180-4 when installing Office

Fix 1 is Microsoft's first solution and works on most connections. Fix 2 to Fix 4 remove what blocks the download. Fix 5 is for a PC that was reset or still holds an old Office. Fix 6, a short pause of the security app, comes last.

Fix 1. Install Office with the Office offline installer

15 to 30 minutesLow riskEveryone with error 30180-4 on a home PC. It is the first solution on Microsoft's own page for this code.

The online installer streams Office while it installs, so every short drop in the connection can end in 30180-4. The offline installer downloads the whole package first as one image file, and setup then runs from that file without the live download.

1. Close the setup window with Close.
2. Open Microsoft's page Use the Office offline installer and select the Office for home tab. Select Download and sign in with the Microsoft account that owns Office.
3. In the Install window, choose Offline installer from the Choose a version drop-down, pick your language and select Install.
4. When the download ends, open the Downloads folder and double-click the image file, for example O365HomePremRetail.img. Windows opens it as a new drive, such as (D:) or (E:).
5. Open the Office folder on that drive and double-click Setup64.exe for 64-bit Office or Setup32.exe for 32-bit.
6. Wait for You're all set, then open Word or Excel while online and select Accept to activate.
7. Select File > Account > Update Options > Update Now to get the latest updates.

Fix 2. Connect with a network cable instead of Wi-Fi and check the connection

5 minutesLow riskYou are on Wi-Fi, the signal is weak, or the download bar stops at a different point every time.

Microsoft lists a wired connection as its second fix for 30180-4. A cable removes the short drops that Wi-Fi can have, and even the offline installer needs a stable connection while the image file downloads.

1. Plug a network cable from the router into the PC. Many laptops need a USB network adapter for this.
2. Turn Wi-Fi off for the time of the installation, so Windows uses the cable.
3. Select Start > Settings > Network & internet and check that Ethernet shows Connected.
4. Pause large downloads, game updates and video streams on other devices of the same network.
5. Run the Office installer again, or the offline installer from Fix 1.

If the connection drops on the cable too, check it once in order, from Windows to the router: How to check your internet connection in Windows.

Fix 3. Install Office from another network, such as home or a phone hotspot

10 to 30 minutesLow riskYou install at work, at school, in a hotel or on any network that someone else manages.

Microsoft says a work or school network may be limited in a way that does not allow Office to install. On another network the same installer reaches the Office download servers without that limit.

1. Take the PC home or to another place with an internet connection you control.
2. If that is not possible, turn on the mobile hotspot of your phone and connect the PC to it. The Office download is large, so check your mobile data plan first.
3. Run the Office installer on that network and keep the PC awake until You're all set appears.
4. Go back to your usual network. Office then works there as normal, because the block only affects the download.

Fix 4. Turn off the proxy server and the VPN for one installation

5 minutesLow riskYou use a VPN app, the PC was used at work, or a proxy was set up for another program.

Microsoft names proxy settings as one of the four causes of 30180-4. A proxy or VPN sends the Office download through another server, and if that server refuses or slows it, setup stops with this code.

1. Close or disconnect the VPN app until Office is installed.
2. Select Start > Settings > Network & internet > Proxy.
3. Under Automatic proxy setup, note how Automatically detect settings and Use setup script are set. Turn Use setup script off for the test.
4. Under Manual proxy setup, select Set up or Edit next to Use a proxy server, turn it Off and select Save.
5. Run the Office installer again.
6. When Office is installed, put the proxy and VPN back the way they were if you need them.

Windows 10 has the same switches under Start > Settings > Network & Internet > Proxy. Microsoft adds that some networks have more proxy settings than these; on a work PC that is a question for IT.

Fix 5. Remove the old or preinstalled Office, then install again

20 to 40 minutesRead the warningYou reset Windows, the PC came with Office, an earlier Office installation or removal stopped halfway, or you see 30180-4 while removing Office.

A reset that restores the PC maker's image can bring back a preinstalled Office or a Microsoft Store version of it. Setup then works around a half-present product, and a clean start removes that extra variable before the download runs again.

1. Right-click Start and select Installed apps (Windows 10: Apps and Features). Search for office and microsoft 365.
2. Uninstall each entry you do not want to keep with the three dots and Uninstall. Restart the PC.
3. If an entry will not go, open Microsoft's uninstall troubleshooter, select Open when the browser says This site is trying to open Get Help, follow the prompts and restart.
4. Right-click Start and open Terminal (Admin) (Windows 10: Windows PowerShell (Admin)).
5. Check for the Microsoft Store version of Office:

   Get-AppxPackage -Name "Microsoft.Office.Desktop*" | Select-Object Name, Version

6. Only if packages are listed, remove them:

   Get-AppxPackage -Name "Microsoft.Office.Desktop*" | Remove-AppxPackage

7. Restart the PC and install Office with the offline installer from Fix 1.

Microsoft notes that the uninstall troubleshooter needs Windows 10 or later and cannot remove Office 2024; remove that one in Installed apps. Step by step with screenshots: Uninstall a program or app in Windows.

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

10 minutesRead the warningFix 1 to Fix 5 did not help and you use antivirus or firewall software other than the one built into Windows.

Microsoft names antivirus software and firewalls as causes of 30180-4. Some security apps inspect or block large downloads from new programs, and setup reports that as a failed connection.

1. Find the name of your security app: open Control Panel > System and Security > Security and Maintenance and expand Security. It is listed under Virus protection.
2. Pause it for the shortest time it offers: Turn off Microsoft Defender protection for a moment.
3. Run the Office installer or the offline installer from Fix 1.
4. Turn protection back on right after setup ends.

If Office installs only while the app is paused, add the Office installer to that app's exceptions or ask its maker for help. Microsoft also says uninstalling the security app may help; if you do that, install it again straight after Office.

If error 30180-4 is still there: read the setup log

The setup window gives one line. Click-to-Run writes more detail to log files in the temporary folder of the account that ran setup, with the name of the PC and a date in the file name.

1. Run setup once more and note the time it fails.
2. Press Win + R, type %temp% and press Enter.
3. Sort by Date modified, newest first, and open the newest .log file that starts with the name of your PC.
4. Press Ctrl + F and search for 30180, then read the lines just before it.
5. Look for a server address, a proxy name or a timeout. That shows where the download was stopped.

• What to send to Microsoft support or your IT department: the full code 30180-4, the Office product and version, whether you used the online or offline installer, the network type, the Windows version and the newest log.
• When it is not your PC: a network that someone else manages may block Office on purpose. Only its administrator can change that.
• When the offline image also fails to download: the problem is the connection or the provider. Try another network before you change anything on the PC.

How to avoid error 30180-4 the next time you install Office

Error 30180-4 is a download problem, so most of the prevention is about how you install. Keeping the offline image also saves time after the next Windows reset.

Frequently asked questions

What does error code 30180-4 mean?

It means the Office installer could not download Office from Microsoft. The window says Something went wrong and asks you to check that you're connected to the internet. Microsoft says the error can come from antivirus software, a firewall, proxy settings or the connection itself. Your internet can look fine in the browser while setup still fails, because only the Office download is blocked. The quickest way around it is the Office offline installer (Fix 1), which downloads Office as one file first.

How do I fix error code 30180-4 when installing Office 2016?

The same way as for Microsoft 365. Microsoft's page for 30180-4 lists Office 2016 among the products it applies to, and its offline installer page covers Office 2016 too. Download the offline installer while signed in with the Microsoft account linked to Office 2016, open the image file and run Setup64.exe or Setup32.exe. Keep in mind that Office 2016 left support on 14 October 2025: it still installs and runs, but gets no more security updates.

Does error 30180-4 depend on Windows 11 or Windows 10?

No. The code comes from the Office installer, not from Windows, and the fixes are the same on Windows 11 and Windows 10. Only a few menu names differ: Installed apps in Windows 11 is Apps and Features in Windows 10, and Terminal (Admin) is Windows PowerShell (Admin). Windows 10 itself left support on 14 October 2025, so a PC on Windows 10 22H2 gets no more security updates, but Office setup still runs on it.

Why does Office say I am not connected when my internet works?

Because setup needs to reach Microsoft's Office download servers, and those can be blocked while other websites load. A proxy, a VPN, a company or school network, a firewall or a security app can each stop only that download. Setup then shows the same message about the internet connection. Turn off the proxy and VPN (Fix 4), try another network (Fix 3), or use the offline installer (Fix 1), which avoids the long live download during installation.

I reset Windows and now Office will not install with 30180-4. What should I do?

Start with the offline installer (Fix 1), since the code itself is a download error. A reset that restores the factory image can also bring back a preinstalled Office or a Microsoft Store version of it. Open Installed apps, search for office and remove what you do not use, then run the PowerShell check from Fix 5. Restart and install your own Office from the Microsoft account that owns it. Your documents are not affected by any of these steps.

I get error 30180-4 when I try to uninstall Office. What now?

Users report the same code while removing Office, often after an earlier installation stopped halfway. Microsoft's uninstall page offers its uninstall troubleshooter in the Get Help app for Microsoft 365, Office 2021, 2019 and 2016; it needs Windows 10 or later and cannot remove Office 2024. If Office came from the Microsoft Store, the PowerShell command in Fix 5 removes it. If neither works, Microsoft has a separate page for removing Office manually.

Is error code 30174-4 the same as 30180-4?

They are close relatives. Both end in -4 and are reported with the same message asking you to check the internet connection, and the same fixes apply: the offline installer, a cable or another network, and the proxy, VPN and security app checks on this page. We read Microsoft's page for 30180-4 only, so we cannot confirm that Microsoft treats 30174-4 exactly the same way. If the steps here do not help, read the setup log as described above.

Do I have to turn off my antivirus to fix 30180-4?

Usually not. Microsoft lists antivirus software as one possible cause, but it puts the offline installer, a cable, another network and the proxy settings first. Try those before you touch your protection. If nothing else works, pause a third-party security app for one installation only and turn it back on right after setup ends, as in Fix 6. Do not leave it off, and do not browse or open other files while it is paused.

Where do I find the offline installer, and is it safe?

It comes from Microsoft. Microsoft's page Use the Office offline installer has a Download button for home plans; you sign in with the account that owns Office, choose Offline installer in the Choose a version list and save an image file such as O365HomePremRetail.img. Work and school plans use the Office Deployment Tool instead. Do not use Office images from other websites: they may be altered, and you gain nothing over the official file.

I searched for this error in another language. Is this the right page?

Yes, if you saw Error Code: 30180-4 in the Office setup window on Windows. Readers who searched in Spanish, Czech, Chinese or other languages asking what it is or how to fix it are in the right place: start with the short answer at the top. Readers who cannot uninstall Office, which some searched for in Spanish, will find the steps in Fix 5. If you searched for the aka.ms/office_setup address, that is a Microsoft link, not an error; this page is about the setup error.
