You don't say what model/year Mac but with a non M1 Mac you can install Windows natively using Boot Camp Assistant, Boot Camp - Official Apple Support, or in a virtual machine using Parallels, Fusion or VirtualBox.

BobTheFisherman is absolutely correct, you need to install Microsoft Windows on your Mac. The current version of Windows is likely to include that Microsoft NET framework, or better.

Those sound like the low-level requirements for Microsoft Windows. Those should not be needed on your premium quality Macintosh computer which already has excellent built-in networking.

what App is this exactly?

The "Mac Pro" is a 42 lb silver tower. Not exactly portable.

The "MacBook Pro" is a family of notebook computers with built-in 13-in or 15/16-in screens.

You only need the complexity of VirtualBox if you wish to run Windows and MacOS concurrently.

If you only need to boot up each in turn, you can just use Bootcamp Assistant to install Windows as an alternate Operating System.
