Looks to me like you have checked "Use launching application" in the Run 
Parameters, but enterd no valid shell path/name below it.

Simple solution: Uncheck that option, AFAIK it's only required to run 
console applications on Linux, or other projects which are not 
self-contained (runnable) executables.

When a launching application really is required, enter a valid 
application in the edit box.
