Scan for Virus/Malware
Your Windows Installer could be malfunctioning because it has been infected with a virus or malware.
Viruses and malware usually attach themselves to system files and hijack the functionalities of the program, usually prioritizing their own execution over the program’s function, thus breaking it. Sometimes, they can also create a duplicate file, which gets called instead of the actual system program, which could be the case here as well.
Run an anti-virus scanto see if this is the case, and fix it.
Restart Windows Installer Service
Your could be having problems installing orremoving programsbecause the Windows Installer Service is not functioning properly. If you are seeing error message related to the Windows Installer Service (e.g., Windows Installer Service could not be started), you should check to see if the service has stopped.
