cannot install ghost-mouse 2 on my 64bit vista os

i cannot install the program because it is not compatible with my 64bit os. is there any way for me to convert it or make my operating system change to 32bit to run it?

tried microsoft virtual pc but the program stops and asks me to reboot or insert boot media, not sure where to go from there. i might be able to find a copy of XP and install it on a partition, but thats really not very helpful for what i intend to do which is to automate mouse movements and clicks to run while i am away from my computer.
