I know I need to use a 64 bit version only of windows on Catalina.

if I wanted to use windows via parallels on Mohave I know that is 32 bit but would I still use Windows 64 bit?

I have access to windows 10 bit only 64 bit. If I need to use 32 bit it would have to be windows 7.

I just want to make sure I use the right version for Mohave when they give me the key.

thanks,
Jim

Your post seems to conflate several different things. Just to make sure you understand the differences:

Catalina only allows you to run 64-bit Mac apps, but this has nothing to do with running Windows.

Boot Camp provides an easy way to run Windows natively on your Mac. With Boot Camp, you start up your Mac and Windows loads just as it would on any PC. You can also switch to macOS by changing your startup disk and rebooting into that. macOS and Windows run independently of each other.

Parallels runs Windows (and many other operating systems) as a “guest operating system” in a virtual machine, running on top of macOS. macOS is the “host operating system.” Basically, macOS and Windows run simultaneously.

64-bit Windows has been required for Boot Camp for a long time now (long before Catalina). Parallels will run almost anything, whether 32- or 64-bit (and even very old 16-bit operating systems from 30 years ago).

You can run Parallels version 15 on Catalina, Mojave, High Sierra, or Sierra, using 32- or 64-bit Windows as a guest operating system on any of these versions of macOS. Use whatever version of Windows is best for your situation, but unless you have a specific need for 32-bit Windows (you almost certainly have no such need), use the 64-bit version of Windows 10. If your Mac already has Catalina installed, then stick with Catalina as the host operating system, as well.

thank you very much for explaining this. I fully understand now. I am using parallels for sure on Mohave.

I totally understand Now. I’ll just get a key for Windows 10 64 bit.
Thanks for the help.
