Minecraft won't open AT ALL! Help?

1 emerald 10 replies 16,508 views | started 04/27/2013 4:45 pm by Wizardofdoom
When I double click on my minecraft.exe it won't open AT ALL. It doesn't even open the launcher! Why does that happen. The java version I have is 7. Does it need to be 6 or 5? Is there another problem with it? Can someone please help me?

1. Go right click on your MC launcher
2. Click Properties.
3. Click compatibility
4. Check the box that says "Run this program in compatibility mode for"
5. Select your OS on the drop down.
6. Click apply. (Bottom right corner).
7. Click OK.
8. Run minecraft

The problem would stem from a corrupted Java install, as the .exe launcher is just essentially a wrapped .jar file.
Open command prompt by pressing the Windows key (looks like a flag on your keyboard) and R, then type in cmd. Press enter.

In the black window that appears, type in
java -version

If a message with "java is not a valid command" or along the lines of that, then you have a corrupted or missing install.

I would recommend uninstalling all versions of Java present on the machine via the control panel or you could use the JavaRA tool to remove all traces of Java. Then, grab the latest version of Java here.

After doing all that, then try running Minecraft.

Re download it. If that doesn't work, I'd recommend you get MagicLauncher. it's boss.

I'll try magiclauncher because I've already tried redownloading it. Yet, it might not work because technic launcher and ftb aren't opening either so yea...
