I was trying to run this Rabindra Rochonaboli in Vista and stuck in a runtime error saying "Permission Dinied". Can anybody pls put some light on this issue?

NB: Deamon Tool dosn't work with vista due to some conpatibility issues and I was using VirtualCD9 to mount the ISO Image. The error is nor from the virtual drive, its from the Rabindra Rachanaabali applicaation.
