Hello,
Microsoft has issued a tool to correct your Windows problem.
https://support.microsoft.com/en-gb/...led-or-removed
If this tool doesn't work, I advise you search for the error message to find other ways to fix the Microsoft Installer as this is a local issue with your computer.
Kind regards,
Alban
