ZOOM & DAW on WINDOWS

[Scarlette]

My co-worker and I are musicians and we need to be able to share musical projects together through our DAW ( in this case Reaper) In real time with audio and video. I am able to share my Audio a Video seamlessly though my iMac, however my co-worker is using a Windows machine and does not have Zoom listed as an audio device within his reaper audio settings? We both run the same versions of reaper. Does anyone have a solution to why I have the option to select Zoom in my audio devices and he is not?

 Thanks!
