Can OpenCover get code coverage with Microsoft.Moles.Runner and Nunit?

I'm using OpenCover with Visual Studio2010 professional. It works well with NUnit on a command-line.

OpenCover.Console.exe -register:user -target:"C:\bin\NUnit 2.6\bin\nunit-console.exe" -targetargs:"C:\App\Test\ApplicationTest\bin\Debug\ApplicationTest.dll"  -targetdir:"C:\App\bin\Debug" -output:html\result.xml

The result is below.

However it doesn't work with Microsoft.Moles.

OpenCover.Console.exe -register:user -target:"C:\Program Files\Microsoft Moles\bin\moles.runner.x86.exe" -targetargs:"""C:\App\Test\ApplicationTest\bin\Debug\ApplicationTest.dll""  /r:""C:\bin\NUnit 2.6\bin\nunit-console.exe""" -targetdir:"C:\App\bin\Debug" -output:html\result.xml

This result is below.

The result of tests are both correct but no coverage is there.

I tried to change the argument of moles, example '/args:"/domain=Multiple"', -oldType etc, but it never works.

Does anyone notice me what I should do? Can OpenCover use moles with Nunit?

I solved the problem by myself. At first, adding below. set CLRMONITOR_EXTERNAL_PROFILERS={1542C21D-80C3-45E6-A56C-A9C1E4BEB7B8} s135.codeinspot.com/q/2342744 – axt_star
And I knew NUnit version is more important. v2.5.2 is worked properly. but v2.6 isn't. – axt_star
this has been discussed in previous stackoverflow questions stackoverflow.com/questions/7013990/… - the issue here is that moles is also a rewriting profiler and so the two clash - however you can inform moles that it needs to 'chain' to opencover (or any other profiler) so that the two will work in sync – Shaun Wilde
I greatly appreciate your comment. – axt_star

I solved the problem by myself. At first, adding the below code into the batch file or set it as command-line command.

set CLRMONITOR_EXTERNAL_PROFILERS={1542C21D-80C3-45E6-A56C-A9C1E4BEB7B8}
