I am not sure if this is your problem but i do know that mc 1.6.4 sometimes doesn't work with java 8. It does however work on java 7 and you can have multiple versions for this kind of things. Other than that, i am not sure if it is a problem but some packs (pretty sure blood and bones is included) need more than 1g ram max. I usually go with 4g for medium sized pack and 2g for super light packs. Let me know if it still doesn't work and i will try it myself with the same packs and see. Good luck ;)

If you mean 64 bit and 32 bit then use 64 if you can, it works better with modpacks

So, will Minecraft 1.6.4 identify with Java 7 if I have Java 7, and 8?
I'm gonna try it with allocating 3.75 GB RAM.

EDIT: It still won't launch, same error. I even deleted then reinstalled the launcher.

You actually have to tell mc to use the java 7 version. If you don't it will just use the defult one

Edit: forgot to say that in he newest version of the ftb launcher you go to advanced options and there you can choose
