Many applications not working after Quicktime downgrade gone wrong.
I have: MacBook Pro, OS X 10.4.11, Tiger
After the most recent Quicktime update (I think 7.5), AVI files that were moved or added afterwards would play video, but no audio.
I tried to uninstall Quicktime in order to install version 7.2. I deleted the QT files from the Application and Library folders.
When I tried to install QT 7.2, I kept getting a message that the 7.2 installation couldn't be completed because a newer version was already installed.
I downloaded Pacifist and used it to install QT 7.2 and restarted the computer.
When it rebooted the info that is normally in the upper right side of the screen is gone: the time, airport status, sound status, Spotlight icon, etc. And the Spotlight icon flashes randomly, but nothing happens if I try to open it. Quicktime still wasn't installed and now iTunes won't open, it just has a message saying "The application iTunes quit unexpectedly." Same with MS Word, iCal, GarageBand... The only applications that seem to be working are Safari and TextEdit. But Safari closes and displays the same message when trying to play a Youtube video.
I tried installing Quicktime again, without Pacifist, and it said the installation was complete and restarted. However, Quicktime won't open at all now, the icon jumps in the dock but nothing happens.
I also just found a Leopard installation DVD - if I installed it, would it be like starting from scratch with a working system? Would it wipe out all my files?
Any ideas?
