Codec issue with some CBT's, video or audio or both would not play

Have received mails regarding issue in running CBT material from our group members.

Problem Description :
Symptom: either video or audio or both will not work.
Error message: on video panel you might receive something similar:
# video not available, cannot find vids:divx decompressor #
product: Learnkey training.
OS: winXP Sp2

Information :

When OS plays a sound or video, it uses CODEC which would compress & decompress the audio or video file to play. If this compression algo is not installed, you would receive such errors.
Now the call of action is to download the specific codec, or download a package of common codecs and get running. I prefer K-lite codec pack, does the job, and it's neat.

In order to find out whether the codec is present or not in XP, do the following:
control panel >system>hardware>device manager>sound,video and game controllers>video codecs>properties>properties

Action :
1. Download K-lite full pack from here: http://www.free-codecs.com/
2. Locate k-lite Codec Pack on the left and follow the link to get the codec, "current & full version", Current is K-Lite Codec Pack 4.4.5 full, the file would be klcodec445f.exe.
3. Install with default settings.
