The new minecraft laucher NOT working!!!

Today i decided to play some minecraft, when i opened the minecraft launcher it said that there has come a new launcher, it said that you should just delete the original laucher and just use the new one, but when i cliked on the new launcher nothing happend. I have tried so much but i cant make it work, i also cant find the app in downloads or anything, it only exict in the search bar, I cannot move it either. What do I do!?
