Quantum XL runs in Microsoft Excel on Windows operating systems. See Quantum XL System Requirements for more information.
Please take care to download the correct version (32-Bit or 64-Bit) of Quantum XL. This must match the Office version that you have installed on your PC. For example, if you have the 32-Bit version of Office then please download the 32-Bit version of Quantum XL. The button below links to a page which can help you determine if you have the 32- or 64-Bit version of Office. A common point of confusion is that Windows can be 64-Bit while running Office 32-Bit, so please base your Quantum XL download on your version of Office, not Windows.
