A few days ago I upgraded Windows 7 to Windows 8, and now I have a bunch of Premiere Pro projects (and After Effects) that are reporting that the majority of AVI files (but not all) that had worked fine on Windows 7 are now unsupported or damaged on Windows 8, and are unusable in the projects. I have copied the files over to my laptop, which still has Windows 7, and they all work just fine.
I am also unable to play AVI files on Windows 8, but that would be a problem with the OS itself. But why are these AVI files now unsupported in my Adobe products on Windows 8?
Exactly what is inside the files?

What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037
Report back with the codec details of your file, use the programs below... a screen shot works well to SHOW people what you are doing
Thanks for the links! In using Gspot, I noticed that the AVI's were using Camtasia's TechSmith codec.
Long story short, my home computer had a fresh install of Win7 before the Win8 upgrade, so the TechSmith codec didn't exist. My work laptop has Camtasia on it, and the Camtasia build installs the appropriate codec. So, the solution was for me to just install the trial version of the latest Camtasia on my home machine, which installed all the appropriate codecs, and now my Adobe products properly identifies and plays the TechSmith codec AVI files.
While doing the research on it, I noticed discussions with people claiming that there was a standalone 32bit version of the codec, but not a 64bit version. Not sure if that is still the case, but installing the Camtasia trial version, and then uninstalling it, works just fine (and gives the latest version of the 64bit codec).
