I had a very common problem with installing minecraft forge 1.6.2 that was : Unpacking packed file scala-compiler-2.10.2.jar.pack.xz

but after following one of this site's post i found out that i had to open it in cmd for getting it fixed but now i'm having trouble with this

Give more ram :

java -Xmx1536M -jar minecraftforge-installer-1.6.2-9.10.0.804.jar

Now i'm getting this when im trying to open my minecraft forge from launcher and it's not coming up

[luacs1998]

Delete .minecraft/libraries and reinstall forge. It'll take a while to start minecraft after that because it needs to redownload all the libraries.
