Why do I get a NotSupportedException when running MSpec on TeamCity?

When running an MSpec build step in TeamCity I am getting the following error in the team city logs:

[Step 7/7] Starting: C:\TeamCity\buildAgent\plugins\dotnetPlugin\bin\JetBrains.BuildServer.NUnitLauncher.exe #TeamCityImplicit

I have made the suggested modification to the machine.config and the MSpec config file, but it does not seem to help.

<runtime>         
  <loadFromRemoteSources enabled="true"/>
</runtime>

The MSpec runner is referencing a compiled DLL locally on the build agent that runs correctly locally in Visual Studio. Can anyone explain what this error means and how I might go about resolving it?

Can you check the properties of mspec.exe or the "compiled DLL" to see if there's a security Unblock button. I had the same error and Unblock fixed it. Enabling loadFromRemoteSources didn't help.
