First, thank you so much for the tool - I used 22.214.171.124 to try to update my Dell Studio 17's drivers (running Vista 32 bit). However, after installation using the modded install, my driver version number has updated (to 8.522.0.0), but my Catalyst no longer runs. When I right-click the desktop I see the option for Catalyst, but clicking it does nothing. Similarly, clicking the "launch ATI Catalyst" button in the Advanced Settings tab under Display Settings does nothing. Any ideas how I might resolve this?
