Can't attach Debug Engine for Intel MIC architecture

Hi, all:

I want to debug Intel Xeon phi application on VS2012, and I follow the file below:

https://software.intel.com/en-us/articles/debugging-intel-xeon-phi-appli...

But when I want to attach to process, it always fail.

Can anyone tell me what wrong is it?

Thanks.
