Ok it's work ! How can I get several .exe versions with steam? For example the a16 and the a19? just put a copy of the game with the right version on my desktop and change beta on steam and do the same one again?

Hey guys ! I'd like to play older versions like the a16.4 or the a19 but when I choose the betas in the Steam properties, my game run but it never launches after a loading time Is it currently possible to play on older versions?
