Microsoft – Windows Media Player – Unable to Play “GoTo Meeting” Video

Found myself reviewing or at least trying to review some Instructional videos from Idera’s web site ( this morning.

And, the web site had the following message:


Media Player Error Message Help

You’ve encountered error message C00D10D1 while using Windows Media Player. The following information might help you troubleshoot the issue.

Codec is missing

Windows Media Player cannot play the file (or cannot play either the audio or video portion of the file) because the G2M3 codec is not installed on your computer.

The missing codec might be available to download from the Internet. For more information about codecs, see Codecs: frequently asked questions.





Per-using “Web Help” indicated, that we were missing the “G2M4” codec.

From Goggling, was able to determine that G2M4 is a CODEC manufactured by GotoMeeting.

The CODEC is available via:

Installing the CODEC allowed us to view the video.

As an aside, though we have used Gspot Codec tool ( to identify which codecs multimedia files are encoded with in the past, we could not do so at this time.  To use GSpot the actual media file will have to be available. But, the media file is not quite available during a Video Streaming Session.
