Just ignore this - I am an idiot - Thread Checker just starts with vTune as the default project type. you have to change to Thread Check project type
I'm glad to see that you have worked out the issue, andI will address it herein caseother users have the same question.
Thread Checker can be used without a VTune license on Windows. It will install the necessary VTune files, but only the Thread Checker tools will be available from the VTuneGUI. To use the VTune tools you need to have a VTune license.
