Premiere CS6 hanging on ExporterAVI.prm after an upgrade from Vista 64bit SP2 to Windows 7 How do I fix Premiere CS6 hanging on ExporterAVI.prm after an upgrade from Vista 64bit SP2 to Windows 7?  It hangs indefinitely but was working fine before the OS upgrade.  No unusual CPU usage or memory usage, it just sits there forever.
This is most likely related to an AVI codec not loading properly after the upgrade.  In my case, I had the Matrox VFW software codec installed.  Uninstalling it and installing the newest Windows 7 version fixed the problem.  Clean up your installed codecs and reinstall updated versions of the codecs you need and the problem should be resolved.
