When trying to update, there comes an error message, saying s.th like:
"The file "C:\User\Desktop" is not a valid installation package (... ...)."
Also, deinstallation from "Control Panel" --> "Programs and Features" is not working.
Months ago I used a cleaner named "WinInstaller Cleanup", an deleted every file the program was able to find. I think there lies the problem: A missing uninstallation file for my NT 8.0.17 installation.
I would need info how to completely manually deinstall NT, or
would need that missing file.
OS is Windows 10 Professional.
Thank you very much in advance!
