Minecraft Hack Client Help 1.6.2!

Hey guys, I keep trying to install hack clients on MC 1.6.2, I even got help from a friend who knows a lot about it but it still doesn't work.
What I do;

Open Run
Go To .Minecraft
Open Versions
Make New Folder Called Hacked Client
Delete The 1.6.2 Jar, and .json
Add Hack Client Jar, and .json
Close out
Go To Minecraft
Press login

After I press login it processes and everything then says finished with 1 failure. Someone please help!

For 1.6.2 its different, because you cant just use the same jar due to the fact that you have 2 minecrafts now, and to solve it you have to make your own folder in .minecraft to put the hacks in, i had the same problem and my buddy helped me .
