Step 1: You have firepro driver intalled ? yes, and have problem ?
1°: Open C:\
2°: Open Firepro Driver Folder C:\AMD\14.502.1019-WHQL-FirePro-WindowsX32X64
3°: Go to \Packages\Drivers\Display\WB6A_INF , in this fold have more 2 folders, B181879 "this folder change name in other drivers" and CCC2, OPEN B181879
4°: Search DLL atio6axx.dl_ and use 7-ZIP for open DLL, user use the right mouse button " http://i.imgur.com/GGCYbFu.png "
5°: Pick DLL, and DROP ONLY THIS DLL ON C:\Windows\SysWOW64 and restart system, try work in cinema4D or other program do you have problem.
EDIT: LAST DRIVE DON'T FIX THIS PROBLEM, PLEASE AMD FIX PROBLEM, USERS DO NOT NEED TO MAKE MODIFICATIONS TO THE DRIVER WORK.
Edit2: Sorry guys, problem not solved, I forced the cinema 4d and the problem returned.
