I am writing for a friend of mine (not very tech savvy) who has been having this issue on his Lenovo laptop with an FX-7500 + R7 M260DX.
The system supports crossfire
The issues began after updating to Windows 1709 + driver 17.11.1, it happens with any DX11 game/application when launched.
I have tried installing 17.7.1 drivers as well as 17.11.2 but they won't install.
After the installation the Radeon settings panel says that there is no GPU driver installed, I tried with a clean install and with DDU, nothing works.
It's almost as if Windows refuses to install the GPU drivers during the installation, the other components are installed.
DX12 is unaffected, FIFA 18 works well with 17.11.1 as long as it runs in DX12 mode.
I reinstalled the DirectX End-User Runtime as well as the various C++ redistributables, if I recall correctly the Direct X installers cover up to DX 10, while DX 11 and 12 are "baked" into Windows.
Is there something corrupt in Windows or is it the driver causing the issue?
I haven't tried any other driver due to time constraints, do you happen to know a driver version that installs fine on laptops under Windows 1709 other than 17.11.1?
It has been more than a month and aticfx64.dll still crashes all the DX11 games I try to launch.
The driver installation often fails as if it didn't detect the GPU, the control panel mentions that there is no AMD Gpu connected. It installs properly only once out of five or so tries, and after wiping the system with DDU each time.
Please look in to this issue.
