"Hi Dear All,

I very much appreciate if anyone can help me to install the CII 5.1.
I've Windows professional 64 bit and already installed the Windows XP mode/virtual PC 64 bit but am not able to get the CII running. I guess my v5.1 is bundled for 32 bit OS.

thanks in advance"

I think that was not clear, I should have said; it's Windows 7 professional 64 bit.
Your advice, on how to run CII v5.10 on Windows 7-64 bit, is appreciated.
