I installed SHIII to the C:\Ubisoft\SilentHunter III destination folder and it worked just fine. Also, I knew that installing as administrator with Windows 7 compatibility mode would be the right way to go. The rest of your instructions are found in your installation manual.
I want to thank you for this excellent supermod and all that you have done and will do to maintain your work. When I upgraded to a new P.C. in 2013, this game was not one of my legacy software that refused to install.
It has been two and half years of waiting for a way that would allow me to enjoy again, one of my favorite simulations of all time. It has please me to no end. Thank you again so much!
