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)
