Search/indexing is a win feature not OL feature

If the sfc/DISM process does not complete or fix errors found, then you need to start testing your system hardware

Dear Richard,

May I know if you have tried using Office uninstall support tool suggested in my last reply to uninstall Office apps? As you mentioned “I have tried to uninstall Office 2021 Pro and reinstall it but I have the same problem that Office doesn't finish re-installing itself”, may I know what happens when you try opening any Office app (such as Word or Excel) from Start menu? Do you get any error? If so, please provide us with the screenshot.

Your patience and understanding are highly appreciated. Stay safe and have a nice day.

I have received no help from Microsoft Q&A Community - Office, nor from this blog! I still require urgent help with this problem.

Yes, it is Office Pro Plus but i have a similar problem on my notebook, which has Office Home and Business 2021.

Thank you for your help and I will try your suggestions first and see how they go.

Cheers, Richard
