Oh wow I'm apparently to blame cause the installer doesn't start... You're calling me an idiot but you can't even tell me what I'm doing wrong... Forget it, not worth it. I have a better chance on 4chan or Yahoo Answers. Thanks for nothing.

Tried, got the same error.

Yeah I have no idea what that means.

I've copied the installer is in the jre7 folder if that's what you mean.

Entered this: C:\Program Files\Java\jre7\java -jar minecraftforge-universal-1.6.4-9.11.1.917.jar Got this: Error: Unable to access jarfile minecraftforge-universal-1.6.4-9.11.1.917.jar

Doesn't work for me. I reinstalled it 9 times. Tried the 64bit version (the one I normally use), the 32bit version, both versions together, tried installing them in different locations, nothing. The .jar installer still doesn't open. Also tried command prompt and got the same error as you. Tried associating the .jar file-type with Java RE manually, still nothing... What I haven't tried is installing .NET Framework 3.5. I know some installers actually require 3.5 instead of 4.5, but 3.5 no longer installs on my current OS (Windows 7 Ultimate 64bit). Thoughts?
