Capt. Jack,
Hope you're here.
I tried your suggestion below..
Didn't work.
I don't care anymore...I'm using Open Office with no trouble.
Problem is, all my programs have to be right clicked, run as Administrator, and approved to make changes.
Can you please tell me how to undo the changes and get back to normal?
Thank you.

3. Restart the computer to check the issue.
After this, please try to install the Office program again.
