In which folder of the computer is the registration form of Red Alert 2?

Red alert 2 needs to be registered to run? Just kidding ... but there are still some registry files, just don't know what's the use ... there are Regsetup.exe (the icon is a circle with a cross in the middle) and Setupreg.exe (or you must register. Exe First, the icon is a party emblem), so it should be enough to execute it all at once.
