I get an error with Office apps after upgrading to Windows 10

If you encounter issues with your Office applications after recently upgrading to Windows 10, or you have a new computer with Windows 10 installed, see Known issues with Office and Windows 10.

I don't know which account to use.

Check that you're signing in to Office 365 with the correct account.

Install simply failed without reporting a specific error.

You might need to uninstall and reinstall Office. If you're on Windows, you can try the Fix it tool to uninstall Office. If the Fix It tool doesn't remove Office, you might need to remove Office manually.

After you've removed Office, reinstall Office.

How do I know that I have the right operating system?

Make sure you meet the minimum system requirements.

Office will not install on Windows XP or Windows Vista.

If you're not sure of your operating system, see Check to see which Windows operating system you're running or try What's my OS? for Mac.

The Install button won't install Office.

This could happen for several reasons.

For more information, see Install button doesn't install Office.

Why is Office taking so long to install?

Here are the most common causes.

  • Make sure that Office isn't actually already installed.

  • Restart your computer, switch to a wired connection, and install again.

  • Temporarily turn off antivirus software.

  • Uninstall Office and then restart the install.

    For details, see Why is Office taking so long to install?

Note: There's an issue in Windows 10 where if you have more than 512 apps you can't find the Office shortcuts on the Start menu or under All apps. For a workaround, see Office apps are missing from All apps on Windows 10.

I get a "Stop, you should wait to install Office 2016. We’ll have to remove the following if you continue." error when I try to install Office 2016.

When you install Office 2016 as part of your Office 365 subscription, you’ll see this warning if the computer has specific versions of Visio 2013, InfoPath 2013, SharePoint Designer 2013, or Project 2013 installed.

The installation process has to uninstall the programs listed in the warning, and you won’t be able to install the programs again on the same computer. You can install these programs on a different computer.

Issue

Solution

I get a message that my subscription has expired, but I just purchased or renewed my subscription.

To keep your subscription active, you have to sign in at least once every 30 days. If your subscription has not expired, Office will reactivate the subscription the next time you log in.

A subscription notice appears when I open an Office 365 application.

This issue doesn't apply if you're using Office 365 for business   

If you see a notice to buy or renew your Office 365 subscription when you open Word, Excel, or another Office program:

  • Your subscription may have expired

  • Office may have been deactivated for your computer

  • Office may not have been activated when you installed

For details, see A subscription notice appears when I open an Office 365 application.

I get the following message in Office after switching Office 365 plans: “Account Notice. Your Office 365 subscription has a pending change. To keep using your applications without interruption, please sign in now.”

To fix this, uninstall the version of Office that came with your previous plan, and then install the version of Office that comes with your new Office 365 plan. Learn how in “Account Notice” appears in Office after switching Office 365 plans.

This error typically means that you're not using a valid product key. For help, see Error code 0xC004C060.

This issue doesn't apply if you're using Office 365 for business   

Run the Fix it tool to uninstall Office, and then install Office.

When I try to sign in to my account, I see "The account isn't associated with this Office product".

This issue doesn't apply if you're using Office 365 for business   

This happens if you're not signed in with the email address and password that you used when you installed Office so you'll need to sign out and then sign in again. See "The account isn't associated with this Office product" message when I try to sign in to my account.

Even though I uninstalled Office, it's still listed on the My Account page.

This issue doesn't apply if you're using Office 365 for business   

After you uninstall, you'll also need to deactivate the install.

I get an error when I try to install Office 2013 for two different countries.

Issues only for Office 365 for business administrators

Issue

Solution

I'm an admin and don't have an option to install Office.

  • When you first sign up for Office 365 and you try to install Office you might see a message that says you can't install Office because you don't have a license. This could happen because of a delay between your initial sign in and Office 365 for business setting up your environment. Try signing out of Office 365 and then signing back in. To check that the license is assigned, go to Settings Click Settings> Office 365 Settings > Edit Profile and look under Assigned licenses on the bottom right. You should see all the products and services you are now licensed for. See What Office 365 product or license do I have? for more information.
