The icom usb driver fails to install on my windows arm machine. Has anyone found a work-around for this? I'm Running Parallels on a M4 macintosh...

Trying to get VAR AC working on a Macintosh running windows under parallels, and using an IC7300. I think VARA is working ok, and VAR AC appears to be set up correctly, but no com ports are showing up in the drop down list on settings. This version of windows is set up for ARM machines as is my M4 Mac mini. Has anyone found a fix for this issue or suggestions of things to check? thanks
