Silverlight / AMD Catalyst Issue – Graphics device’s driver certificate is invalid 6036 January 4, 2014

Once again a story of woe. With regards to my secondary PC/entertainment setup I outlined here, that I had basically two important needs: I need to have a fitting picture for my Toshiba HDTV = needing a graphics driver to set underscanning / scaling to 0 and I need a perfect software/driver setup so I can instantly watch DVB-T television. Okay with my very specific setup between the “right” AMD Catalyst Driver and all the other software I have achieved these two needs.

Now slowly a third need emerged. Not quite as high priority but well. I recently tried out watchever.de and now I am trying lovefilm.de. Both are Video on Demand services extremely similar to netflix or hulu plus. Both services use a Silverlight player with heavy DRM measures.

And the basic issue now is: Something is wrong in the setup between Silverlight, my PC, the graphics driver or any other component that has a part in playing a video.

I have tried all the suggested steps to fixing faulty silverlight playback. A lot of websites are mentioning something like this:

Well none of these common techniques helped in my case. I must also mention in Watchever there was no specific error message. But fortunately in Lovefilm something was shown. It reads:

Title not available. System Exception: 6036 An Error has occurred.

Well that is at least something. If you read up on it.. Microsoft is clearly saying something is wrong on the DRM side. In fact the specific description of 6036 on Microsofts Dev Net reads:

Graphics device’s Driver Certificate is invalid.

Oh man. Other people say that the encrypted (HDCP) path between graphics card and Screen/HDTV is not valid or there is something wrong in that line of encryption. I quickly verified that my system is generally fully HDCP compliant by using the Cyberlink BD 3D Advisor. It’s a handy utility which checks pretty much everything related to Blu-Ray playback on your PC (and HDCP and driver stuff is an important part of it). Well no issue here on my PC.

So graphics driver.. I use the AMD Catalyst Package 12.10 for my Radeon HD 6800. Should be okay. Quick web search: I am not the only one having this issue. It really seems some messy dirty corner between the AMD driver and Silverlight. Somehow causing the Silverlight DRM stuff to thing there is something wrong and playback should not start. Absolutely horrible. I poked around tried some stuff (i.e. reinstalling Playready components and reinstalling Windows Media Player none of which helped!).

So for now the only Solution I found: uninstall the Catalyst Drivers for example with the build in installer or with the AMD Cleanup Utility. Once completely uninstalled restart your system and then open Lovefilm Netflix or whatever. Voila the Video plays with no issue. But: of course with no proper AMD driver (maybe Windows picked some generic driver or you are just seeing some sort of 800x resolution). Just for fun I tried a lot of Driver combinations Catalyst 11.5 – 13.3 but none of these would work for me.

So summary: If you have the 6036 issue – All the web seems to know right now is that it’s an issue. If you’re really desperate you can uninstall the driver and the Silverlight DRM videos will play. But with no proper graphics drivers this is not a permanent solution rather a quick fix.

I fixed my issue (after I tried all of the recommended options) by installing Windows Media Feature pack
