Hi Mark, A follow up to the "Program Compatibility Assistant" issue on Win 7. If I uninstall my test app and runtime, then open a new command prompt with "Run as administrator" the error goes away and both the runtime and app are installed properly (though the progress bar UI still appears.) I've asked the developer that implemented this feature and he believes this is by design. If you get a chance, could you give that a try and see if it helps? I should note however if there's any problem with the install, for example, the app is already installed and the installer exits because it won't overwrite, that dialog will once again appear. Thanks, Chris
