Class Factory not open mpeg file

I keep getting the error message, “Class factory cannot supply requested class” and so it will not open the file. I believe its a codec but I cannot find out what I need to download to help. Anyone any ideas please :-)

Hi carol

what actully you try to play or run,[Class factory cannot supply requested class]it can show if u run some programswhich not support some file format,in other way , if u want to run format that the program doesn’t support it , it will show this message to you.

can u give us more information about the problem...

I was trying to open an audio file, it was an MCSE Audio book. Although I have had this happen on a few occasions with other things.Any help would be gratefully appreciated. I have tried downloading other codecs but there seem to be hundreds about. :-)

i think if u have an audio book, when you put the cd in tray the cd automatic show u a window from the company that made this book you have)something like interface to cd, there u can play the video
(if the interface made by Demoshield or macromedia director then u must play the cd by Autorun it

wait did you try to run the audiobook cd on audioplayer (not the computer)if it will play then maybe u not use the Anaolg cable

[Technical:Analog cable is (cable that connect from back of CD-Drive to Soundcard to play Audio.cd sound)

hmmmm technology been reach high, becuase this is first time i heard that there were some books like MCSE avalible on audio like this way
