Bravo fosamax ! The thread you found corresponds exactly to my problem :
"if Qt library is compiled with SSE2 and machine does not have the SSE2 support, your Qt application will crash with "The application failed to initialize properly "0xc000001d"" error message."
I didn't knew that the Solarus editor was made with QT and unfortunately i have never used this framework, so there is probably not much things to do. At least I have a clear explanation on the origin of the problem, c'est déjà ça.
Thank you
