"Not Implemented" exception with Visual Studio 2010 code coverage test

I upgraded from VS2010 Professional to Premium in order to use the built-in code coverage testing facility. To make sure I was using the testing tool properly, I went through a small example with C#, which worked fine and showed me what code in my little test had executed. Then, I went through the same steps with the actual application to be tested, which is a C++ app, making sure to build with the /Profile linker switch.

I could run my application in the debugger, and it ran fine. Trying to run the code coverage test, however, failed when exception HRESULT: 0x80004001 (E_NOTIMPL) was thrown, apparently by Visual Studio itself. (At least, the Label on the dialog's title bar says "Microsoft Visual Studio".)

While I appreciate the irony of Visual Studio throwing a "not implemented" exception, I can't imagine how I'd go about tracking this down.

Thoughts?
