Install QuickTime version 7 and reboot your computer.
If that doesn't solve it, uninstall AE, run the CC Cleaner tool from Adobe, THEN reinstall AE and update it to version 11.0.4.
Thanks for answer ! i made it but unfortunately still doesn't works. Any other ideas?
What happens when you try to launch it now?
exactly same 3 error messages. Nothing changed.
You ran the update to 11.0.4 and it still doesn't work? How did you run the update?
CS6 works just fine on Windows 7, so something is awry on your system!
