How to install mods to a cracked minecraft launcher?

I downloaded a minecraft launcher that was cracked, and it was for 1.7.2, and I want to install mods, but all the tutorials have it to where you need to sign in with a username and pasword. Mine has that function, but when I try it, a window pops up saying 'Java Runtime Environment 7 error'. I'd like to get instructions on how to install mods without signing in.

I just don't know what to do?

Okay so this is a question about gaming

I'm a fan of sandbox games.
I played a game called ROBLOX when I was younger, then moved on to minecraft and I finished of garrys mod tonight. I just got bored with it and i'm about done playing it. I had about 1500 hours of it and I love the creative aspect that all these games have.

I just don't know what game I should play next? Is there any left that are these types of games?

I need something useful to build in minecraft?

I've been playing a survival island on minecraft and I need to something to do on it. Now remember it's a world with only one small island so I don't have at villagers. I do have animals and I started a animal farm. Also I have made a mod spawned so that I can kill mobs. But I need something else to build that will help me and be useful!

Minecraft mods aren't working?

I'm playing minecraft 1.6.4 and I have optifine and carpenters blocks on the game already. Both work fine. I was building some thing and wanted something that came from a different mod, so I put that mod in my folder (already downloaded it, it worked fine before), but it won't show up. At all. I'm using some of the Life in the Woods pack stuff, like the dynamic lights and weapons mod, but those won't show up in game. The game runs fine, but the game won't show the mods I put in the mods folder. Anyone have an answer?

Good and cheap gaming laptop?

What is a good and cheap gaming LAPTOP? I can't sent up a desktop in my room. I'm not very old so under 1000$ please. I need something that has good graphics and can run 50+ fps on the following games: Minecraft (with mods… Feed the beast and such), DayZ, and COD.

Why is Minecraft running so slow?

Minecraft runs really slow on my computer.
Alienware X51
8GB RAM
64 Bit
Intel(R) Core(TM) i5-2320 CPU @ 3.00GHz 3.00 GHz
Windows 7 Home Premium Service Pack 1 (ACTIVATED)
Cracked - Yes
MagicLauncher_1.2.5
Mods - Yes
Forge - Yes
Modified.jar - No

That is more than enough information for any type of help. If you say "You probably don't have enough RAM/Memory/Anything to run Minecraft." Then I obviously don't need help from said person. I run:
Assassin's Creed Brotherhood
Payday 2
South Park- The Stick Of Truth
The Sims 3
Dolphin - TLoZ(OOT, MM, TP, SS)
Unturned - Steam
Rust - Steam
Portal 2 - Steam

So now that you have an idea of what I can run, and my circumstances, help?
