If you have been using Windows 8, Windows 7 or Vista, then for some of the apps that you install, you may see messages like the one in the picture below.
Program Compatibility Assistant, a feature which is in Windows since Windows Vista, is the cause of such dialog boxes. It was created to help the end user to resolve potential compatibility issues with installed software. Often, this message 'This program might not have installed correctly' turns out to be a false positive and appears even for portable apps which do not have installers.
