1. Browse to "C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore\CineForm"
2. Delete the file called, "CFHD_AVI_Importer.prm"
3. Relaunch Premiere Pro.
That should resolve the issue.
Note: By removing this Importer, deep color support will no longer available. An alternative to removing this plug-in is to change your Premiere Pro project settings to select software only in the Mercury Playback Engine drop-down menu.
