I don't have AVIC, that is only on AM4 AFAIK :[

Thanks but I did all this and it still is giving me a code 43 D:

I also tried re-installing windows 10 but still no dice.

When I try to install the driver manually from the .msi I receive a
message that it is not compatible with the version of windows that I
have...maybe that is because my gaming VM has no network connection and
hasn't been windows updated?

The resources tab is not populated with the AMD driver installed only
populated when I have just the generic driver there.

When installed via the .inf
"Windows found driver software for your device but encountered an error
while attempting to install it"
And of course
"Windows has stopped this device because it has reported problems. (Code
43)"

I really want to use my new card :'[ any other ideas?
