I cannot even install the driver. I ran ddu, restarted, then tried to install the driver. Partway through installation I get a blue screen with stop code "SYSTEM THREAD EXCEPTION NOT HANDLED," and saying that atikmpag.sys failed.
I had the same issue but that was without DDU use, I tried to update the driver by installing it over the other one, after reboot I used DDU and it worked make sure you reboot after each step..
