I've installed Forge for 1.6.4, inserted bunch of mods, turned them all into .jar and when I enter my client and click play it just disappears. I get no log or error message. In Task Manager it shows javaw.exe for a brief second, but it immediately disappears.
I've tried:
Deleting .minecraft and downloading MC and Forge again.
Removing all the mods and trying to start Forge with no mods (to assure non of them is bugging it out).
Downgrading to Java 7 (some people had the same problem with Java 8).
Different version of Forge for 1.6.4.
Nothing works! I'm seriously at my nerve's endings with this.
Also, it has to be 1.6.4 because of some of the mods, but that shouldn't even matter. And yeah, normal Minecraft works normal the whole time, with every version of Java and everything, it just won't load modded.
Edit: I'm using Windows 7 OS, 64 bit, with Java 7 installed for both 32 and 64 bit.
All the mods I'm using are 1.6.4. The mods are:
IC2
Big Reactors
Archimedes
Simply Jetpacks
Ars Magica 2
Blood Magic
Thaumcraft
Witchery
Buildcraft
Dartcraft
Carpenter's Blocks
Industrial Craft
Magical Crops
NEI
I'm not sure what you mean by this. All you're supposed to do is install forge, and then into the newly created mods folder you dump your downloaded files (zips or jars) exactly as they are when you download them.
Yeah, sorry for not being more precise. I did insert them into the mods folder as .zip files, but they weren't working, so I converted them to .jar. I don't know if doing that had any point, but I tried. But Forge doesn't work at all, even without mods, so that's the problem.
No do not convert any of the files manually. Leave them exactly as you downloaded them unless the mod instructions specifically tell you to do anything with them.
For now, take out all the mods, go to mc launcher, hit Edit Profile and select keep launcher on at all time. Hit save profile. Then start your 1.6.4 forge mc version. After it fails, go back to your mc launcher and copy paste contents of launcher log + game output here.

You need http://files.minecraftforge.net/LegacyJavaFixer/legacyjavafixer-1.0.jar in your mod folder.
Would that work with Java 8 too, or do I have to stay downgraded?
