I found it is an OS issue. "INSTMSIW.EXE" is for NT based systems.

"INSTMSIA.EXE" (Which comes packaged with Visual Pinball) is for 9X/Me systems.

I don't have "INSTMSIW.EXE" on my system, and can't seem to locate it (for download) at microsoft.com

Anyone know where I can d/l it?

Thanks (Again),
Trebor
