@Shikijo Alright Goku. Try using 'Revo Uninstaller' it cleans out all the junk from your registry. Just an example of a good Uninstaller software.
I say this because unless your registry is cleaned of the original files from your previous installation, you will be wasting your time trying to re-install Sauer.
Good bye Guest......... Have a nice "real" life..... I sincerely hope you are one of the "Pro" Players that is on my List of people there is no point in me playing against....
BTW.......... Believe it or not reality is in the eye of the beholder!
