I am having problems installing Trainz 2004 and 2006 and paintshed discs.When i first bouight this computer i had no problems installing them at all.Then as luck would have it we had McAffee virus software and we signed on to the internet and here McAffee sent out a virus to all of its users which caused our computer to crash and i had to reformat our drive and reinstall all of the software.That was several months ago and i decided to reinstall my Trainz discs and no matter which disc i put in i keep getting the message that setup or install are not valid win32 applications.I didn't have this problem when i first installed them it installed flawlessly.Now i cannot install any of them so can someone please help because it is one of my favorite sims to play but can't.My computer hardware is well above the requirements that it needs to run.What i have is a dual core Intel Pentium 2.5 ghz that can be overclocked to 3.8 ghz but that i haven't done and i have 2 gigs of memory along with an Intel built in video card that i can allow up to 256 megs of video memory and that is what it is set at.As i said i had no problems installing it before this happened so why now.please help Brian
