How to determine what type (32-bit or 64-bit) of software will work on my computer?

Following these steps on a Windows operating system, you can determine whether your computer is 32-bit or 64-bit:

1. Open the System Information
Open the Start menu, and click on Programs -> Accessories -> System Tools -> System Information

2. Look in the System Summary
The System Information tool will display detailed information about your Windows operating system.
Once opened it will show the “System Summary” it’s an overview of your computer and operating system.

3. Look for the System Type Item
On the right-hand side of the window you will see a list of items. Look for the item called “System Type”.
The value of this item will tell you whether your computer is 32-bit or 64-bit:
