I got the RX470 running Crimson ReLive Edition 16.12.1. I had 16.12.2 running same problem. The eyefinity setup simple install says " Your display config has changed band setup not be completed. to restart then click retry",when retry is clicked it just loops. The exception unknown exception(0xe0434352) occurred in the application at location 0x00007FFDFCFD7788, is what I get with advanced.
