Not every application has jumped into the Windows Vista/7 era, and portable applications can be confusing to both of Mircrosoft's newer operating systems. Prevent Windows from asking, every single time, if your program "installed correctly" with a quick system tweak.

If you run a good number of portable applications, or have to install a good number of oldie-but-goodie apps, you're probably familiar with a Windows dialog that pops up after installation finishes, suggesting that "This program might not have installed correctly," then asking for you to confirm whether that's true. It's an extension of the Program Compatibility Assistant Service, which watches executables as they run and checks to see if they're trying to pull off operations in an older fashion.
That's fine to have happen when you're occasionally installed older apps, but if you get sick of getting the pop-up window every time you run a portable application or any other app, the gHacks blog points out a fix—but it 's one you should only use if you don't plan on dealing with any older Windows apps any time soon. Head to Windows' Services configuration (type services.msc into your start menu), then look for Program Compatibility Assistant Service and double-click it. Stop the service, change it from Manual to Disabled, and hit OK.
It's fairly easy to bring the compatibility helper back—just head to Services again and switch it back to a Manual service. The helper can be actually helpful, but if its help to headache ratio is a bit too low for your tastes, this is an easy means of nixing it.
