    Can't go back from Catalyst 13.4 to 12.8 - OpenCL.DLL is missing


      I toied to update Catalyst driver on my APU A10-based PC from 12.8 to 13.4 (latest available for this PC).


      Upgrade went OK, but I discovered that my app works slower than before. So decided to downgrade back. Uninstalled Cat 13.4 completely, rebooted, installed Cat 12.8. - all openCL apps fail including clinfo - no OpenCL  DLL.

      Uninstalled 12.8, installed 13.4 - works (but slower), again unistalled 13.4, rebooted (after each action), installed 12.8 - no OpenCL.dll.


      So? For what reason driver contains "uninstall" option if it can't be uninstalled in reality? Is this normal situation?

      What should I do now to remove traces of 13.4 and restore OpenCL environment based on 12.8 drivers ?
