Setup.exe Disappears on Win7 64-bit

[bikeracer4487]

I have KOTOR2 on 4 CD's that I've tried installing from, I also tried copying one CD to my hard drive and starting setup.exe from there and I tried downloading the CD's from...other sources...and installing using those and it's the same thing every time. It says "Starting Installshield wizard." and then I get a progress bar in a smallish window that fills rapidly and then that window disappears and nothing happens. I can see setup.exe in the task manager but there is no window, and if I try to run setup.exe again I am informed that another instance is already running. Also, if I click and drag the window with the progress bar while it is filling, the progress bar stops and won't continue until I release the mouse button. I have tried running it in WinXP SP2 & 3, and Win2000 compatibility modes and with and without "Run as Admin", all with the same results. I recently replayed through the entirety of KOTOR1 with no issues, would REALLY like to be able to play this game...not sure why it has more issues than the older KOTOR1...
