When I try to open up my Minecraft launcher, a popup comes up and says Downloading Runtime, it only loads until there is a few mb left to load but then another pop up shows up and states that it is unable to update the Minecraft launcher. I tried restarting my Minecraft, re-installing it and updating Java but nothing has worked.

  • Have you tried reinstalling Java entirely?

Have you modified your Minecraft version? If yes copy your current .minecraft folder(C:\Users\yourusername\AppData\Roaming.minecraft) Obviously replace yourusername with your username for windows. For Mac or Linux see the following website http://www.howtogeek.com/207484/how-to-find-your-minecraft-saved-games-folder/

Then reinstall minecraft and java (completely), and try it out.

If that doesn't work, you may have a problem with your PC and could have a virus. If that is what you end up with, go to the stack exchange with that type of Q/A.
