How do I fresh-install my codecs?

Hi. I wanted to view QuickTime movies using the XDCAM EX codec on my Mac, which is installed as part of the "QuickTime Pro codecs" package. But in order to install that package you need FCP X, Motion 5 or Compressor 4. I didn't have one of those pieces of software installed, so I tried to manually install all of the codecs from the downloadable .pkg file. It worked for every codec except for Apple Intermediate Codec. It looks like that one can't be upgraded while OS X is running.

I'm now able to view XDCAM EX movies, but I'm getting stability problems. It's really not working out.

Now I've installed Motion 5 just to see if I can do a clean install of the QuickTime Pro codecs package. But I can't. When I run the QT Pro codecs package, it says that a new version of the software is already installed on my hard disk. Under /Library/QuickTime, I see that the AppleIntermediateCodec.component is 0 bytes.

Any ideas how I can clean-install my codecs?

Problem solved

I solved the problem, folks. For future reference, here's what I did:

1. Boot from a Mac running the same version of OS X, but one that doesn't have the QT Pro codecs installed. Mount the internal hard disk of the problem machine. (Note you can do this from the problem machine itself if you boot from an external hard disk or from another Mac in target disk mode).

2. Nuke the entire contents of /Volumes/Macintosh HD/Library/QuickTime/ on the problem Mac. (Or even better, archive them somewhere else).

3. Copy the contents of /Library/QuickTime/ (on the working machine) to /Volumes/Macintosh HD/Library/QuickTime/ on the problem machine

4. Boot from the problem machine, and run Software Update. The machine should immediately try to fresh-install your codecs.

....voila.

Thanks for that tip. I would never have thought of that. Makes sense though.
