There is a problem with OpenGL in the Crimson Driver which is what causes the LoadLibrary error 87 which is an error message for OpenGL failing to open in OpenGL applications.
I get this with Adobe software which uses OpenGL for AMD cards and the only fix is to remove the driver completely with Display Driver Uninstaller 18.104.22.168 and then you install the Catalyst 15.10 Beta drivers, you can find them here: AMD Catalyst 15.10 Beta Driver Download at Guru3D
I recommend doing that until AMD solves this issue or someone finds a workaround with the OpenGL file.
There is finally a fix for this issue which is mostly isolated to mobility series of Radeon.
The fix to this is to use the last working OpenGL files, I have extracted these from the last working Catalyst 15.11.1 Beta.
Its a regular .ZIP file with the following inside:
Clean old drivers with Display Driver Uninstaller 22.214.171.124
Install Radeon Crimson 15.12 (Do not use 15.16 Beta as I am not sure whether the files will work with it, the installation causes BSOD on my Windows 8.1, you could try if you like and report back)
Replace atig6pxx.dll, atig6txx.dll and atio6axx.dll in C:\Windows\System32
Remember to backup these files, you can simply just write atig6pxx.dll.BAK behind them and then copy the new ones from the .ZIP file, ignore the atiglpxx.dll, I do not really see any use for it in Crimson but I kept it just in case.
