I installed CS5 master collection trial version on W7 64 bit machine.
After Effects doesn't load at all (it stops at "initializing user interface") and it's even impossible to kill the process in windows (never had this problem with any app). I can shut down all the other processes, like dynamiclinkmanager.exe or Adobe QT32 Server.exe, but aftereffects.exe just won't stop and I need to restart my PC.
Also Premier crashes after I click 'new project', or try to open something, but the application starts and I do see the whole GUI.
I updated Quicktime, as well as my video card drivers. All other apps in the master collection seem to work fine. Uninstalled the whole thing twice (with the remove preferences option), cleaned the registry with a comodo system clean up utility, reinstalled also twice- nothing. Tried with the firewall turned off and quick time completly uninstalled - nothing changed.
