Step 1: Sign in to Office with the right account
If Office asks you to sign in, enter the account you used to buy Office. You’ll see “We couldn’t find any Office products” if you use the wrong address.
Try this: Sign in to Office
Step 2: Check for multiple copies of Office
You may not realize you have more than one copy installed. Having two installs can cause activation conflicts.
Try this: Check for multiple copies of Office
Step 3: Check your subscription status
If your subscription has expired, you’ll see “We couldn’t find any Office products.” Renew your subscription to use Office 365.
Try this: Check your subscription status
Step 4: Troubleshoot activation
If Office still won’t activate, choose your Office version for additional troubleshooting help.
