Do I have 32bit or 64bit Excel/Office

by Philip Mayfield


Quantum XL is fully compatible with Windows 32bit and 64bit. However, at the time of writing Quantum XL must be running on  32bit Office/Excel. By default, the Office installer will install the 32bit version. However, if you would like to double check, then follow these steps.


Note: Excel 2007 and earlier are all 32-bit.

Unfortunately, for some reason Microsoft decided to make this harder to do. First, select "File" from the main menu.

Then select "Account" from the menu on the left.  On the right side of the screen is a small box with the words "About". Despite lacking any visual indication that this is a button, it actually is one. Click on this button.
