Hi,
You will need a license for this. You have received a Demo License with the registration, so register the license.
Then you will have to use the following command
<Target Name="TestWithTypeMock">
<TypeMockStart Link ="NCover" ProfilerLaunchedFirst="true"/>
<Exec ContinueOnError="true" Command="$(NCover) $(NUnit) Test.dll"/>
<TypeMockStop/>
</Target>
if this doesn't work, please send the value of the following registry key:
HKEY_CLASSES_ROOTCLSID{6287B5F9-08A1-45E7-9498-B5B2E7B02995}InprocServer32
