If you can't install Microsoft 365 because the Install button isn't working, it might be because of the following.
The install button is greyed out
If the Install button is grayed out, your Microsoft 365 subscription might have expired. Select your subscription from the list below to see the steps for how to renew it.
- Renew Microsoft 365 for home
- Renew Microsoft 365 for business (only Microsoft 365 admins can renew this type of subscription)
Nothing appears to happen when I select the Install button
If nothing appears to happen when you select the Install button, try one of the following options.
Option 1 - Select Run to start the install
You might need to choose the Run button (or the equivalent button depending on the browser you're using) at the bottom of your screen to start the install. See Download and install or reinstall Office for step-by-step help.
Option 2 - Use InPrivate browsing
Try the private browsing option for your browser.
- Right-click the browser from the task bar and select New InPrivate window (or depending on your browser, New incognito window or New private window).
- In the new window, go to m365.cloud.microsoft/apps, sign in with your Microsoft account or work or school account.
- Select Install, and then Install again.
Option 3 - Delete your temporary internet files
When you delete your temporary internet files, your links and favorites won't be deleted. However, the list of websites you've visited, cookies, information entered into web forms, passwords, and other temporarily saved information will be deleted.
In Edge, type Alt + F, and then choose Delete browsing data.
In the Delete browsing data dialog, choose a Time range, and select the Cached images and files checkbox and any other item to remove.
Select Clear now. This can take a while if you have a lot of files.
After the files have been deleted, sign in to install Office.
Option 4 - Reset Microsoft Edge settings
- Follow the instructions in What to do if Microsoft Edge isn't working.
- Install Office.
