Have a program that will only install and work on 32bit vista or xp business/professional systems. Toshiba Laptop I use is a 64 bit machine and currently has win7 64bit home on it. I am considering to install on seperate partition Vista business 32 bit os . Will i be able to use program on that partion/ os ? Main point is will the Vista 32bit act as 32 bit or will it install as 64 bit and be of no benefit for my program ?
