ok thanks! the reason i want to stay in 1.7.2 is because i am looking at this cool mod called elemental guns mod and it will only work in 1.7.2 (well I mean minecraft still loads up but crashes upon loading up a world) so otherwise i just use 1.7.10 because that's where all the mods i have are curently in

got it in the spoiler
ok thanks! the reason i want to stay in 1.7.2 is because i am looking at this cool mod called elemental guns mod and it will only work in 1.7.2 (well I mean minecraft still loads up but crashes upon loading up a world) so otherwise i just use 1.7.10 because that's where all the mods i have are curently in
thank you so much!! it worked!! thanks again for taking the time to help me
delete all of your mod then try again if it doesn't work simply go in versions in your .minecraft folder and delete 1.7.2-ForgeXXXXXXXXX-1.7.2
and install forge again of try reinstalling java maybe downgrading to java 7 works.
how do I down grade to java 7?
