To find out which specific assembly is throwing a fit try using the Fusion Log Viewer. It's extremely helpful in situations like this.

It should be in your visual studio program group. Just be sure to right click on it --> run as admin the first time so you can adjust the settings.
Thanks James. I copied all of the DLLs from an empty project and was able to get past the error.
