Disable Windows 7 Program Compatibility Assistant “This program might not have installed correctly”

March 18, 2010 | Filed under Windows 7


Whenever you install a software in Windows and if you cancel the setup or sometimes even when a program has successfully finished installation, you will get an annoying dialog window from Program Compatibility Assistant telling you that “This program might not have installed correct”. You get to choose whether to Reinstall using recommended settings or This program is installed correctly.

This program might not have installed correctly

This new feature in Windows 7, the Program Compatibility Assistant is meant to detect known compatibility issues in older programs. After you have run an older program in this version of Windows, it notifies you if there is a problem and offers to fix it the next time you run the program. If the compatibility issue is serious, the Program Compatibility Assistant might warn you or block the program from running.

If you prefer to have more control over the program compatibility and doesn’t want this assistant to nag you all the time, you can easily disable the Program Compatibility Assistant from the Windows Services. Click the Start Menu button and type services.msc at the Search Programs and Files bar. Scroll down and look for Program Compatibility Assistant Service, right click on it and select Stop.

This takes effect immediately without rebooting. By default this service is set as manual and once you have stopped the service, it would not be started when Windows is booted up until you manually Start it back again. Theoretically, disabling a service that you don’t need would somehow make your computer faster.
