Installation issue : it doesn't start any application


I have just installed VS 2008 Shell and Ironpython Studio, and can create new applications, but when I try to debug them or generate executables, the IDE seems to work but doesn't start the application.

This is the Output I get :

------ Build started: Project: WindowsApplication3, Configuration: Debug Any CPU ------
========== Build: 1 succeeded or up-to-date, 0 failed, 0 skipped ==========

If I generate an executable, it compiles correctly but raises an Violation when I try to run it.

I guess I need to install some prerequisites or setup some paths, but I don't know what.

Thanks for your help.
