Windows 10 has been reported as having issues with USB webcams in general, which is very unfortunate. AMCap is also getting old.
I would approach the problem as follows (we will do it as soon as I can get a windows 10 machine installed here):
- try to get a regular USB webcam working with skype or such
- get Open Broadcaster Studio from https://obsproject.com/download
- make sure it works with a regular USB camera
- then it should just work with JeVois as well.
