Exception for "Bad security permission set blob" when loading a reference

Hoping someone can help me with a bit of an obscure problem. I couldn't find any documentation or people who had run into this before.

When running FxCop (1.36) on my dll, it tries to load another dll of mine which is a reference. When it tries to load, it throws the following exception which I have no clue where to start with.

Can anyone provide some insight?

Thanks!

Hi,

Could you please provide us with more information, say, Operating System, since the error might be due to some new checks in FxCop 1.36 that were not run before.
