Software Programs & Drivers - What runs on 32-bit or 64-bit computers?

Still confused about what the terms 32-bit and 64-bit are all about. Simply these numbers refer to the way our computer's processor or brain (what you hear referred to as the CPU), handles information.

64-bit handles large amounts of random access memory (RAM) much more quickly and effectively than a 32-bit system

Most programs designed for a computer running a 32-bit version of Windows will work on a computer running 64-bit versions of Windows, however major exceptions to this are:

• many (if not most) antivirus programs and
• some hardware drivers, including those for flash drives and printers

Drivers designed for 32-bit versions of Windows don't work on computers running a 64-bit version of Windows. If you're trying to install a printer or other device that only has 32-bit drivers available, it won't work correctly on a 64-bit version of Windows.
So if you aren’t sure or need help updating drivers or other troubleshooting issues with drivers for 64-bit versions of Windows, contact the manufacturer of the device or program
