Excel help does not work

One suggestion is to try signing out of your user account and signing in as an administrator.

Then, check if the issue persists in the administrator account.

If the Help feature works in the administrator account, you can try going back to your user account and see if the issue has been resolved.

Another suggestion is to try starting Excel in safe mode by pressing and holding the "Ctrl" key while starting Excel.

In safe mode, go to File --> Options --> Add-ins --> Manage COM Add-ins --> Go, and then untick the boxes for all add-ins displayed on the window.

Then select OK, quit Excel, and reopen it in normal mode (not safe mode).

A Windows and Office update is always advisable in advance!

I hope this helps!
