Office 365 programs won't open

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
