I recently switched a user over from Office 2013 32-bit to Office 2013 64-bit. They already had the 32-bit version of NumXL installed (1.63). Now that the computer is running Office 64-bit, NumXL (understandably) does not work. However, when I attempt to uninstall NumXL 32-bit it gives me an error saying I need to have Excel 32-bit installed. Do I really need to go back to Office 32-bit just to get NumXL 32-bit uninstalled?
