[Windows] The Windows Installer service could not be accessed on Windows?
August 4th, 2009
I’ve had a lot of people run into this issue from time to time. You may think it’s an issue installing Skype, or AIM, or whatever else you are experiencing this error on. The problem actually lies within Windows Installer.

“The Windows Installer service could not be accessed. This can occur if you are running in safe mode or if the Windows Installer is not correctly installed.”
The following command should fix this issue in most cases:
- Go to Start > Run > type in CMD and press enter
- Now type in msiexec /unregister in the command prompt
- Then type in msiexec /regserver in the command prompt
- Restart the computer and try installing your software again- it should work now
