Minecraft Forums

Alright, so recently I decided to download the latest version of Forge to Minecraft. After using the Forge Installer, it set up everything the way I assume it is required to be, listed below;

• Configuration: Default
• Environment: 1.6.2-Forge9.10.0.790
• Minecraft.jar: 1.6.2 | 1.6.2-Forge9.10.0.790.jar

At this point, the only mod I have at the moment is Forge. Immediately after viewing it over, I attempted to launch Minecraft from Magic Launcher, only to fail. The launcher closed, but no Minecraft. No crash report was shown, leaving no answer to what was wrong. Afterwards I tried launching it from the normal 1.0.10 Launcher, running on the profile "Forge." Minecraft once again failed to load, leaving this for me to see:

Launcher 1.0.10 (through bootstrap 4) started on windows...

I am not sure what this means, and it would be greatly appreciated if I could get some help with resolving this problem.

I have some what the same problem, tho my development console on the un-altered launcher from minecraft.net says an "exit code 1" and blaims the minecraft.class file inside of the minecraft.jar for forge modloader -.- why is it doing this T_T

Me too. After the game has launched, I am checking the task manager. The process javaw.exe (which is minecraft) showed up for 6-14 seconds and it disappeared without warning.
