Running a vb.net .exe file

I everyone.

I created a vb.net .exe file, and it's working while i'm debugging running in visual studio, or directly executing the .exe file generated to bin folder.

Now i'm trying to create a mapkey to run that .exe file. But no success.  

In mapkey I've insert the the file location in the "os script" tab. But isn't working.

Any idea of how to solve it?
