Most of the notebook / computer nowsday ship together with Windows 7 64 Bit edition.

So, many of them asked me when they buy Windows 7 64 bit edition machine, "Can i run an 32bit application on 64bit machine ?" ?

The answer for this question will be YES ! You still run your 32 bit application on your 64 bit machine.

The 32 bit application will be installed to your "Program Files (x86)" folder instead of your "Program Files" folder and it won't be utilize the benefit that 64 bit machine have.
