Minecraft launcher not work

(sorry for my bad english, I'm french) When I try to use the new minecraft launcher, (in aniway version) he crashed and I cannot played. The new version of The update is made of force and I don't succes to found à old version. I playd minecraft 10/02/2017 the morning and when I stop played, I start the launcher and the update is done without giving me my opinion. I would love to play the game a lot, but I can not play anymore. Thank you for finding the problem. I put you on screen. Thank you very much.
