You will need to upgrade to ATI Catalyst 9.2 or above since the CAL runtime libraries have been renamed to match the rebranding to ATI Stream.

If you have CAL applications which rely on the old runtime library names, please relink against the new runtime library names.

If you have any questions, please do not hesitate to post them to the forum.
