OSX: Client can't install driver when trying to connect to a server->device

Hi, I have the server (trial) set up on a WIn10 machine and have used EasyFind to get the Client to find the server. Every things working up to this point. I can see the server and its USB devices on the client.

When I try to connect to a device, the client starts to install a device driver under OSX and I get an error saying it can't.
I've followed the direction to reboot and try again, with the same result.
Here is the log from the client.

I'm really keen to get this working with the trial to perform some tests for using VirtualHere as a possible customer support vector.

Not sure if this is the same issue. Steps to reproduce are the same. There is no message in Security & Privacy to approve the kext (and I think I did that a while back?).

Very slow to perform the install of the driver (seems like it times out).

I deleted the kext via sudo kextunload /Library/Extensions/vhhcd.kext and then rebooted. It works now.
