MS Fakes/Shims with VS2015 professional?

I am working for a client on a project and existing code/tests are using MS Fakes library and Shims to isolate tests etc... I installed VS 2015 enterprise edition, on a trial, and all was fine. With my MSDN subscription I get up to VS 2015 Professional and now tests don't run, get failure: ``` Failed to resolve profiler path from COR_PROFILER_PATH and COR_PROFILER environment variables. at Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.IntelliTraceInstrumentationProvider.ResolveProfilerPath() at Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.IntelliTraceInstrumentationProvider.Initialize() at Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.UnitTestIsolationRuntime.InitializeUnitTestIsolationInstrumentationProvider() at Microsoft.QualityTools.Testing.Fakes.Shims.ShimRuntime.CreateContext() at Microsoft.QualityTools.Testing.Fakes.ShimsContext.Create() ``` Looking at it the shims is trying to use Intellitrace, which VS2015 doesn't give me. Anyone know a way around this, other than purchasing Enterprise edition of VS?
