Hi all and very thank you for your reply.
In fact I take the "risk" and i have found no problem for the moment, I rename the win32+64 exe, osx file have the good name, and Linux i do not the change for the moment I come back later on this point.
Also, I use some third party programs like inno setup and ressources hacker to make a setup, and change the default icon of the exe files and the software make a "new" exe. for osx I make a .dmg file to help to install on MAC and... no problem for the moment, all works (I hope lol).
I think I will contact scirra to present my game when the Windows store add it and when my site was finish but you can see the result on my actual website :
Thank you I will update the post if any problem occure (i hope not !!!)
