Vista Transformation Pack, specially, is having these problems since its last version. I last version too, to run the installer, i have to press debug after the executable crash and then when Visual C++ Debugger opens the assembly code for it, i had to choose the next instruction from the one that is highlighted and choose, set as next statement. After ignoring the warning and pressing ok, would it run properly. Try it if it helps, i can't tell exact method as i am on real Vista now and have no intention of going back to XP.
