Zbook 14 - AMD Firepro drivers problem

I just bought a Zbook 14 that has the AMD Firepro M4100 discrete graphics card. Running Windows 8.1 x64.

But I'm having a huge problem with the drivers.

I tried to install 13.152.1.9002 from the HP site, but when it comes to the AMD Drivers install step the screen turn black and a restart is forced. When the system has rebooted none has been installed.

Intel drivers are fine.

I also tried the newer drivers directly from the AMD site but the forces a blue screen.
