Hi
Can you check if your OS is 32 bit or 64 bit?
If its 64 you should install TypeMock 64 bit.
If the OS is 32 bit try running a simple test in the command line using TMockRunner.exe e.g
(TYPEMOCK_PATH)TMockRunner.exe (NUNIT_PATH)
unit-console.exe Test.dll
This should indicate if the problem is in the installation of TypeMock or somewhere else.
Please tell me the results.
