Minecraft – Why does the Minecraft launcher not launch the game

minecraft-java-editiontechnical-issues

Some background:

Slightly over a month ago, Minecraft suddenly stopped working on my computer. There was no strange behavior of any kind prior to that. I have tried a couple of usual fixes, such as re-downloading and re-installing both Minecraft and Java (64-bit) itself. Unfortunately, neither of these fixes did anything. Cleaning the registry for leftovers from possibly corrupt Java re-install didn't help either. Then I have checked the firewall, to see if it conflicts with Minecraft or Java, and it doesn't. At last, I checked processes in task manager, and found that when I try to launch the game with the launcher, it creates a javaw.exe process for a split second, and the process immediately disappears.

Here's the log that I found in Minecraft's nativelog.txt:

########################################################
Native Launcher Version: 51  
Operating System: Windows 8.1  
Application Hash: b06079c75cb616544a6dbf83108db9a3265e1242  
Java Version: 1.8.0_25  
x64: 1  
Starting download of: https://launchermeta.mojang.com/mc/launcher.json  
Created pFile  
Content length is 00DF3F68  
Got 200 from server  
Download successful  
Started application ".\runtime\jre-x64\1.8.0_25\bin\java.exe" -cp "game\launcher.jar"   net.minecraft.launcher.Main

Application can still run, so I assume that part's fine. When I launch Minecraft I do the following:

  • I use the newest Minecraft.exe official launcher (alternative Windows download, without built-in java).
  • After that I click the launcher to load, the cursor indicates that it's loading a file, and nothing happens.
  • As indicated by the background above, javaw.exe seemingly closes immediately after the process starts up.

So my question is, how can I get Minecraft back up and running?

My PC Specs:

  • HP Envy -15t Laptop
  • Windows 8.1 64-bit OS
  • Intel Core i7-4510U CPU @ 2.00GHz – 2.60GHz
  • 8GB RAM

I had a similar problem to what you're describing (albeit probably for different reasons, as I'm running a linux setup on a Chromebook); what ended being a passable solution for me was to use Magic Launcher:

It's basically a launcher made to allow for mods to easily be loaded but I basically used it to circumvent the fact that I was having a problem with the official launcher. See if that works as a workaround until someone with a better solution can help out.

If you do end up trying it, I used Magic Launcher and ran the "test" launch from the settings menu before logging in with my own account.

Good luck!
