FIFA 10 is not correctly installed. Please reinstall

Recently while running Fifa 10 setup ripped version, I faced an error stating "FIFA 10 is not correctly installed. Please reinstall". This error is actually pointing towards an improper entry in windows registry for Fifa 10. Just download reg.exe and regsetup.txt file from following link,

Copy paste both files in FIfa 10 directory, overwrite the existing one. Thats it, you are ready to play.
