I'm running a current version of Office 365 for Mac, which includes Excel for Mac (version 16.53). I have the "Family" plan, which would allow me to install Office 365 on up to five computers. I want to run the WINDOWS version of EXCEL (because it is more robust than the Mac version). I want to run that version in a Parallels shell. I assume that I can install Windows Excel only in Windows/Parallels. Does anyone know if having two instances of Office/Excel (Mac & Win) on the same machine will somehow conflict?
