Cannot open Excel (app damaged or incomplete) since upgrading to MacOS Big Sur 11.5

Hello, I cannot open Excel ('You can't open the application 'Microsoft Excel' because it may be damaged or incomplete'). I have noticed this since the latest upgrade to MacOS Big Sur. The Office applications, including Excel, all show version 16.51 but, whilst they all open, Excel doesn't.

I cannot restore from Time Machine (no back-up).

What can I do?

Thank you,

Francesca

PS = Have followed some good suggestions on another page but the resolution there was found by restoring from backup.

Just to let the community know that the solution posted to a different thread provided by Jim Gordon resolved my problem. See below:

  1. Go to the Applications folder.
  2. Drag Microsoft Excel.app to the trash
  3. Restart your Mac
  4. Reinstall Microsoft Excel using this installer
  5. Install package
