Comment 8 for bug 242985

The problem was that in the windows installed version elisa is launched from an executable (elisa.exe), and the code assumed the main executable was python.exe, so running the GstMetadata client runner with elisa.exe did not work (it once did but that was a hack that anyway disappeared).
A fix has been submitted for merge: when running the installed version, replace the name of the executable to run by "deps\bin\python.exe".
