Eclipse code run problem.

[jenya7]

I build a project in Eclipse successfully.

Build complete (0 errors, 0 warnings): D:\Workspace_Eclipse\agro_sense\build

Then I set a COM port in Launch Target and when I try to run I get

Exception occurred executing command line.
Cannot run program "C:\cygwin64\bin\python" (in directory "D:\Workspace_Eclipse\agro_sense"): CreateProcess error=193, %1 is not a valid Win32 application

What can be a problem?

As I understand it looks for a Python executable at a wrong directory. How can I configure the path? And why the path is good when building the project?
