DotCover.exe execution stops

I am using dotCover.exe to generate code coverage result through command line. But during execution it is throwing error "Telerik.JustMock.Core.ElevatedMockingException : Cannot mock 'TestProject.TestProgram'. The profiler must be enabled to mock, arrange or execute the specified target."

and execution will stuck there itself , never ends (I waited for almost 2 days)
