Sometimes, when you run Word, Excel, PowerPoint, Access or other Microsoft Office products will get the "Microsoft Office Word / Excel / PowerPoint / Access has not been installed for the current user..." prompt, even run office as administrator.

This is just nonsense - "I have already installed it for me (current user)"! More tragically, you cannot reinstall it successfully now (it will throw the 1402 error). If you encountered this error, I suggest that you do not believe some experts and their saying due to they suggest you to change the Windows Registry and / or the permissions, this can only lead into a worse situation.

Right Solution:
Run cmd as administrator and execute the following command:
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose



Once done, run Microsoft Excel/Word/PowerPoint/Access or other Office products, it should work.
If still cannot get it working, please reinstall or repair Office, after ran above command, you can already reinstall Office without any error. If you know the answer, please ignore this section.
If don't know, please follow me: press <Win> key -> type cmd -> right-click on "Command prompt" app -> select "Run as administrator", like this:
