I have run the quick and full repair, I have uninstalled and reinstalled 365, I have restarted pc, I have looked for any updates. I go to file explorer and right mouse click on the various .exe program files and it says it can't find the file try to retype it and try again. I have been using these programs for quite a while and this problem just started 3 days ago. Programs work fine on other computer. I have not installed/uninstalled any new programs.

I am running out of patience. Please help

    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.
