Kernel launch fails with most Nsight options

I’m trying to profile a fairly simple kernel using Nsight 3.0 with Visual Studio. If I select any of the three ‘source level’ experiments (instruction count, divergent branch, memory transactions) the profiling goes fine. But if I select any of the ‘kernel level’ experiments, the launch fails with error 30, “Unknown”. Any thoughts on what might be causing this? Thanks!

Hi TimothyMasters,

The latest Nsight is 4.1 now, Could you try a newer version?
