TMX:OD

I installed Catalyst 8.7 today (updating from 7.11) using the Mobility Modder Tool. After the reboot, I tried to access the CCC, and saw a glimpse of the configuration wizard, but before I could even switch to the advanced mode or continue the wizard, the program disappeared from the screen.

I have tried reinstalling Catalyst to no avail, I have even uninstalled all available drivers for it, rebooted into safe mode, and deleted all stray files and registry keys, for an 'as-clean-as-possible' install, once again to no avail. CIM reports that Catalyst installed without a hitch, the install report file declares this as well, but I still cannot access the CCC.

UAC is ENABLED, but I ran the original installer file (the one that extracts to c:\ati\support\...etc...), as well as the Mobility Modder Tool, and Setup.exe under an administrative Command Prompt, so all ran with Administrative Privileges...

Ran antivirus and antispyware software offline [aka off a bootable windows cd] so that no rootkits can have an effect on the results-- system is clean.

anybody know what causes or how to fix this?
