Office 365 programs won't open

Hi, thanks for sharing the fix. Have a good one!

Thanks for letting me know the issue is still happening, and I’m sorry for the trouble. Just to make sure we’re on the same page, were you able to complete all of the steps I sent earlier? If so, have you also tried creating a new local account on the computer and testing Microsoft Office there? That will help us tell whether the problem is tied to your user profile or to the application itself, so let me know what you see, and we’ll go from there.

Hi, let me help you.
Open Command Prompt as administrator and run DISM /Online /Cleanup-Image /RestoreHealth. Wait for it to finish, then run sfc /scannow, and restart. That repairs damaged Windows system files, which a 365 repair never touches. After that, a quick and very telling test is to create a new local user account, sign in to it, and try opening Word there.

Follow these steps to create a local account;

Open Settings, go to Accounts, then Other users (it may say “Family & other users”), and click Add account next to “Add other user.” When the Microsoft sign-in window pops up, click “I don’t have this person’s sign-in information” at the bottom, then choose “Add a user without a Microsoft account.” Type a username, set a password, answer the three security questions Windows Home asks for, and finish.

After that, sign out from the Start menu, pick the new account on the lock screen, and give it a minute to set up. Then try opening Word or right-clicking one of the .exe files, same as before.
