Current Forge Update crashes .jar

[terranproby42]

So I've followed the instructions from the Forge site and every time I put all the files from the Forge.zip into Minecraft.jar I'm given and error from the Java Virtual Machine Launcher saying: A Java Exception has occurred.  It gives me no pathway to find out more about said error.  I've looked through the .minecraft folder that I know where is and there's no crash report file.  The .exe won't even allow me to edit it.  I'm bothered because I've been trying to mod a technic pack modpack but it keeps telling me I need to update Forge for them to work, and here I can't get Forge to update.

if you want a modpack use ftb

Thanks diesieben07, that was actually helpful.  Right up until Tekkit lite won't load and won't give me an error.  The edit to Vanilla is fine, which leads me to believe I buggered Tekkit somehow, but I can't figure out how

If you're attempting to install forge on any technic launcher pack (not like you should), install it to modpack.jar in /bin,  NOT minecraft.jar.
