Visual Studio 2012 - Aspose.Slides Fails to load assembly


Running Visual Studio Professional 2012 (11.0.61030.00 Update 4)
.Net 4.5.51641

I get the following error when trying to Preview Reports in Visual Studio. The assembly runs “fine” on the server located on the same machine.
(I say “fine” because Graphs export as blurry, i am yet to find a solution to this. Exports fine to Excel etc, but PowerPoint exports are blurry… But i guess i should post that in a separate ticket.)

"Could not load file or assembly ‘Aspose.Slides.ReportingServices, Version=, Culture=neutral, PublicKeyToken=716fcc533a201e56’ or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT: 0x80131417) Required Permissions cannot be acquired."

Installation notes:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\PrivateAssemblies
1) Aspose.Slides.ReportingServices.dll ( File version )
With the same permissions as other files in the same directory.

2) RSPreviewPolicy.config added:
<IMembershipCondition class=“StrongNameMembershipCondition” version=“1”

3) RSPeroprtDesigner.config added:

4) PrieviewProcessingService.exe.config “Optionally tested” to add

Perhaps i was un-clear.

It works fine on the server.
It is in the debug/preview enviroment (Visual Studio 2012) that i cannot get it to load the assembly.

My best guess would be that the information given Here is no longer valid (publickey perhaps, since there has been a major release v.5.).

I have followed the instructions there to the point but still get the same permission exception.

Best regards,
