Minecraft Won't Update To 1.12

Question

I can't update Minecraft to 1.12, every time I press play with the 1.12 version, I get this error message:

I tried turning off my antivirus but it still doesn't work. Any ideas?

Answer 1

The process cannot access the file because it is being used by another process.

This probably means that you have 2 Minecraft launchers (or something similar) open at same time.

Here's some fix ideas:

• Close all of your Minecraft launchers and Minecrafts and try again.
• Log out (closing all of your open programs), log back in and try again.
• Restart your computer and try again.
• Delete your .minecraft folder. More info.

If you can't figure it out, Process Hacker can display apps using that file.

Answer 2

Shut down and restart your computer, then launch the client, go to launch options and make sure yours has C:/Users\USER\AppData\Roaming.minecraft for your game directory.

Answer 3

if you go to your .minecraft folder and go in to versions then delete everything in it then load minecraft 1.12.1 it should work.

Answer 4

the problem is the folder natives that probably do not download, It is a bug that can not be fixed, you can try download the version 1.12 from other computer and copy the folder of version 1.12 in your computer
