title: OpenCover shows no results on windows server 2008
body: <p>I'm trying to run OpenCover with MSTest on Windows Server 2008 R2 machine and always get empty results:</p>
  
  <blockquote>
    <p>c:\OpenCover>OpenCover.Console.exe -register:user -target:"C:\Program
    Files (x86 )\Microsoft Visual Studio 11.0\Common7\IDE\MsTest.exe"
    -targetdir:"c:\MyApp\bin" -targetargs: /testcontainer:"C:\MyApp\Tests\bin\UnitTests.dll" -output:c:\cover.xml</p>
    
    <p>Microsoft (R) Test Execution Command Line Tool Version 11.0.51106.1</p>
    
    <p>Copyright (c) Microsoft Corporation. All rights reserved.</p>
    
    <p>Please specify tests to run, or specify the /publish switch to publish
    results.</p>
    
    <p>For switch syntax, type "MSTest /help" </p>
    
    <p>Committing...</p>
    
    <p>No results - no assemblies that matched the supplied filter were instrumented
        this could be due to missing PDBs for the assemblies that match the filter
        please review the output file and refer to the Usage guide (Usage.rtf)</p>
  </blockquote>
  
  <p>The PDB files exist in the specified folder and the profiler DLLs are registered using regsvr (both x64 and x86). Microsoft Visual C++ 2010 Redistributable Package is installed. .NET framework 3.5, 4.5 installed.
  I've tried to run it with and without administrator permissions...</p>
  
  <p>At the same time it works perfectly on my win7 x64 machine with VS 2012 installed so I suppose I've missed some dependancies or this is a security issue.</p>
  
  <p>After removing quotes and spaces I receive a better result but still without code coverage:</p>
