this may be of some help, I had a similar problem when running a setup file. I could see it the program in task manager but nothing on the screen. After much clutching at straws I found the set up window by upping the screen resolution to the max. For some reason the setup was opening a window way off screen when in 600x800. but visible therefore able to select continue when set to 1028x768. on completion of the setup reset the resolution to 600x800 and all was ok.
Good luck
