Hello I am trying to figure out what could be the problem with only one of PC not playing video with Silverlight using Telerik controls. As soon as I open the book that is supposed to play a .ismv file; I get following error in "Inspect Element" on IE & Chrome as well as "Firebug" for Firefox:

 

Uncaught Error: Unhandled Error in Silverlight Application [Arg_COMException]

Not sure what is causing the problem ? I have re-installed both Silverlight and .NET framework on this PC to match the PCs that do work fine and play the video. Only Firefox and Chrome play the video on other PCs but this one gets hung with the same error (mentioned above) in all 3 browsers - IE, Firefox and Chrome. 

The .ismv file was created using MS Expression Encoder 3.0

Any suggestions ? I am trying to help my client figure this out and no luck so far..

Just to add to my original question.. here is an snippet from the reply I got from one if the MS Silverlight forums..

 

"...I can see it's a problem with some sort of com component.Exactly which that is with a Telerik control, I don't know.I would guess the com component is not present or is not registered.  This might be something totally separate from .net and Silverlight.  Maybe part of the telerik stuff.  ..."

Hello PK,

We are not aware of such issue or limitation and you are the first one reporting it. That is why I would like to ask you for more information about the scenario in order to try and reproduce it on our side.
- the OS on the computer.
- the exact version of SL that is installed.
- does the issue only occur with ".ismv" files? Could you please try and run other file with the same format and also try to run file with different format?
- the exact version of the browsers used on the computer.
- do you define and load videos like shown in our documentation. Or you are using some custom code that is out of the ordinary. If you can show us a code snippet of the xaml and file/stream setting will be great.

Looking forward to hearing from you.

Kind regards,
