It isn’t uncommon for something to go wrong when installing, uninstalling, or updating a program on a Windows system. For example, you might get an error message like one of the following:
- The Windows Installer Service could not be accessed.
- Windows Installer Service couldn’t be started.
- Could not start the Windows Installer service on Local Computer. Error 5: Access is denied.
This happens often enough that Microsoft provides a special troubleshooter for fixing this sort of problem. The Fixit can be run at this Microsoft page. The screenshot below shows the Fixit. If you prefer to try to solve a problem yourself, Microsoft also gives instructions for a manual procedure.
