I am having the exact same problem as Rob. I have updated the driver (AMD Radeon R7 M460). It is compatible per system requirements.
I made sure Chief is directed to that driver. So Rob, did you find a solution? I sent my info to Support yesterday but wanted to see if you found
the answer while I wait. (see image below)
