When you are buying a software for your Windows computer, either locally or online, you may be confronted with a question as to the type of your Windows operating system. Am I using Windows 7 or Windows 8 32-bit? Or Windows 7 64-bit?

Determining the bit type of your Windows OS

This is important because you can install a 32-bit software to a 64-bit Windows Operating System, but NOT vice versa. And in purchasing software, the installer of the software that you purchase must be compatible to your Windows bit type, otherwise, it won't install to your computer.
