Ok, I just installed the game as administrator with my anti virus and firewall off. I put it in a program files (x86) folder and the game ran fine so I turned my a\v and firewall back on and tried to get sp1 and the same thing happened again. It get about halfway through the patching process and a message comes up that trainzutil.exe has stopped working and windows will close the program and search for a solution. I minimized the message screen instead of closing it but it stops the patch process anyway. The only thing I can think of is that there`s something wrong like a virus or something so I`m gonna get my computer cleaned out and checked but that won`t be for a month since I`m going out of town to work for a month. After I get that done I`ll try again. It`s not just trainz that I have a problem with it stop working ,it`s happened a few times with other stuff too, that`s why I think it`s the computer and not the game.
