      Workaround

      This issue only happens in the latest beta version of the launcher. To revert back to the stable launcher, please follow the following steps:

      1. Navigate to your .minecraft folder
        1. Press the Windows and R keys simultaneously
        2. Type %appdata% into the text field that pops up
        3. Open the .minecraft folder
      2. Open the launcher_profiles.json file with Editor. (Do not use Word, you must use a text-only editor that doesn't allow for formatting.)
        1. Right click on the launcher_profiles.json file
        2. Select "Open with..."
        3. Select "Editor"
        4. If Editor is not available in that list, use the last option in the context menu to get a list of more programs, which should include Editor. Select it from there.
      3. Scroll to the bottom of the text file
      4. Change "channel": "beta" to "channel": "release"
      5. Save the file, and close the editor

      The launcher should now be able to start again.

      My Minecraft launcher worked, but i did update for have beta version and now the launcher doesn't work i try to starting it as administrator but he doesn't launch. Just nothing happened.

      if I uninstal it and dowload it without delete .mincraft folder the prblem is already here.
      Even if you remove library folder it doesn't work again.
      I try to remove all folder and files 1 by 1 the problem come from the file "launcher_profiles.json" because beta is enable.

      cordially.
