Windows Installer Service Could Not Be Accessed

Windows installer service could not be accessed




Some times when we try to install a program, we will get an error ”The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance.”





The registry under


has been corrupted.




The solution is deleting this registry key and importing the msiserver registry key from another working machine. Restart computer then issue will be gone.
