Hi, sorry to jump on this thread too, but i have the exact same issue.
I have no crash/error 'Logs' as i can't even get forge-1.6.4-9.11.1.965-installer (has a Jar extension) to do anything, either when i double click on it, or by right clicking and using 'Open with...' and selecting the Java Platform SE binary option.
I've downloaded and installed both the 32bit and 64bit versions of Java 7 (which is the correct version for this version of Forge).
On the 64bit version of Java i get a brief dos/command prompt window open (for less than a second) then close so i can't see what it is saying.
On the 32bit version of Java i get nothing at all.
I see that for Forge 1.7.10 (the one after 1.6.4) it has a 'Installer-win' download option, which is an .exe, but their is only a 'Installer' download which is a .jar for version 1.6.4
Is that the issue maybe? The whole reason for getting the older 1.6.4 version of Forge is to play the Life in the Woods mod for minecraft, so if anyone knows of another way to get Forge 1.6.4 to do something, or how to play Life in the Woods on 1.7.10 i would be very grateful!!!
I've run minecraft latest (1.8 ) a few times first, AND also version 1.6.4 that i need for this mod so i know the base Mincraft game is working on both versions.
i've downloaded installed and uninstalled Java 7 a number of times, both the 32bit and 64bit (my PC+OS is 64bit), i've used jarfix, i've made sure no antivirus or firewall software is running, i've mde sure in in administrator mode and all software is installed with administrator rights.
I've watched youtube tutorials on setting up Life in the woods, which includes where to download the right Forge 1.6.4 from (which is the link at the top of this forum). It's just that for me the .jar file does nothing and i can make it do nothing on my PC?
All very confusing and i've not really seen much help around the internet on this.
here is my log from my .minecraft (with some stuff redacted)

--------------------------------------
However as Minecraft works fine, and the issue is Forge 1.6.4 doing nothing, i can't see that would help much
Any suggestion greatly appreciated as i just bought Minecraft today to play this mod!!
