If you’re the type of person who installs a lot of software on your PC *puts hand up*, then you may have seen the following message after successful installations:

Most of the time, the program I am installing installs fine and this message is an inconvenience. In a quest to click my mouse less, I set out to disable this dialog box. Learn how to disable this also in this guide.

Note: This guide involves stopping a service. This service is for the following:

This service provides support for the Program Compatibility Assistant (PCA).  PCA monitors programs installed and run by the user and detects known compatibility problems. If this service is stopped, PCA will not function properly.

Thus, by stopping this service you may have compatibility issues with other running programs.

Disable “This program might not have installed correctly” Message

To disable the This program might not have installed correctly message:

  1. Click the Start button, type services.msc, and press Enter.

  2. Scroll down to Program Compatibility Assistant Service, right click it, and click Properties.
  3. Change the Startup type to Disabled and click Stop.

Now you’ll no longer see this box and can use the saved mouse clicks and time (oh so much time) to browse this site for more tips!

    I have to say that while some people may find this feature of Win7 annoying, the Program Compatibility Assistant has helped me get some important (to me) older software working that otherwise would have been lost. I’ll keep it! :-)
