codec:
Short for compressor/decompressor, a codec is any technology for compressing and decompressing data.
definition from WebopediaYou might check the Microsoft Windows Update site. Click on Start/Programs and go to the Microsoft Windows Update link. Click that and it will open the update service.
Or click here (Windows Update)If you haven't been to the update site previously, you will need to allow the scan engine install (click "Yes" to allow the installation).
I suggest you install all the critical updates, plus any of the others you may desire.
If you see an update to DirectX, I suggest you download that as well. If you don't see a DirectX download, you can get it
here. (latest is DirectX 9.0a)You can check to see what version of DirectX you're currently running by clicking Start/Run
then type
dxdiag
Click OK
This is a diagnostic tool. You can check to see if it shows any of your multimedia files as "problem" files, and you can run the video and audio tests. If errors are found, you can use the "Help" troubleshooters for assistance.
If all this doesn't help, can you post the specified codec that you need? Does your program give you any specifics, other than Microsoft codecs? Please tell us your Windows Operating System version information also.
Codec information/downloads I suggest you use this site as a last resort, since it is quite complicated, though very thorough.
I hope something here will help!
