Depending on the version of Windows 7 will depend on how your experience is. Usually the problems start if you use the 64-bit OS without running the compatibility modes. Not so much with 32-bit OS since it was the standard until Vista popularized the 64-bit OS.
the problem starts from the installation process~~

and i still have the previous folder of heRO before changing my OS
and when i double click that drops icon~~
