Do I have 32bit or 64bit Excel/Office

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.
