AMD confirms Adrenalin 26.6.2 driver fails to launch on Windows 10, recommends rolling back

AMD's Adrenalin 26.6.2 driver, which brings FSR 4.1 support to Radeon RX 7000 series GPUs, has hit a major snag for Windows 10 users. According to AMD, the driver fails to launch properly on Windows 10 systems and instead displays an error stating that the software is not compatible with the installed AMD graphics driver. Device Manager shows a yellow exclamation mark next to the GPU under Display Adapters, and some users are also reporting Error Code 43.

The issue appears to be tied specifically to Windows 10. Windows 11 users are not mentioned in AMD's advisory, and the bulk of reports are coming from Windows 10 installations. That said, a smaller number of users have also reported problems with RX 9000 series cards and even Ryzen 9000 integrated graphics under Windows 10.

AMD's official advisory recommends rolling back to Adrenalin 26.6.1 as a temporary workaround while engineers investigate. The catch is that 26.6.1 does not include support for FSR 4.1 on RDNA 3 GPUs. For Windows 10 users with RX 7000 cards who were waiting on FSR 4.1, the options are limited to either rolling back or using a third-party tool like OptiScaler in the meantime.

AMD has not confirmed whether the fix will come as a new driver release or a patch to the existing one. A timeline has not been given. The 26.6.2 driver also added game-ready support for Assassin's Creed Black Flag Resynced and DOOM: The Dark Ages Revelations, both of which Windows 10 users will effectively be without until a fixed version ships.

If you are on Windows 10 and have already installed 26.6.2, rolling back to 26.6.1 is the safest move for now.
