Unable To Install Computercraft - Need Help

Problem solved, thanks!

Hello, I'm a teacher and I privately purchased Minecraft today because I thought ComputerCraft would be a nice way to introduce my students (15-16 year old) to programming, among other things.. Previously I was using JavaKara for that purpose but I'd like to try something new!
However, I was unable to get ComputerCraft to work. Here's what I did:

1. I downloaded the Minecraft.exe launcher 1.1.2 from minecraft.net and ran it. It runs version 1.6.2 just fine.
2. I downloaded the recommended minecraft forge installer (file is called: minecraftforge-installer-1.6.2-9.10.0.789.jar), ran it and clicked "install client". It said that it installed correctly and I see that there is a new folder called "1.6.2-Forge9.10.0.789" in my /.minecraft/versions folder.
3. I downloaded the latest ComputerCraft called "ComputerCraft1.55.zip" and created a new folder /.minecraft/mods where I put the zip (did not unzip it).
4. I forgot to change my user profile, see http://imgur.com/8aULHHM
5. I launched Minecraft.exe again and started a new flat map in creative mode.

Once I was in creative mode I did not see any computers in the item menu and was unable to craft a floppy disk or any other thing in creative mode. I conclude from this that it didn't install correctly.
Please tell me what I did wrong.

(If you're currently about my teaching activity I'm currently looking into this and if I judge it to be as good as JavaKara I'll ask the school for the money to purchase all the minecraft licences via MinecraftEdu. Should this get through I'd also donate 10% of what we'll spend on the licences to computercraft. I won't upload my course material here though because it will be in german and I don't think anyone will be intersested in that. I can say though that I'd also like to use Minecraft to introduce my students to basic digital circuits because you can build and gates, or gates etc as well as latches and flipflops. Through MinecraftEdu I might even find other ways to use minecraft in the classroom.)

Thanks for your help!

Edit:
Thanks for your help! Yes it was a very small problem indeed. I was not aware that you had to select the user profile as seen in the image I uploaded under point 4.
I must say that I'm amazed at how many responses I got, I didn't know that the ComputerCraft community was that active!

For those of you who asked about to course material, I usually start the programming and boolean logic section in the second half of the semester, so I won't rewrite most of it until then. I haven't looked into ComputerCraft enough to know whether I'll really be using it, but if I do it will be based on what can be found here: http://www.swisseduc.ch/informatik/karatojava/kara/materialien.html

Split into new topic.

When you launch Minecraft, and it comes up to the initial Singleplayer/Multiplayer screen, does it list a Forge or FML version in the bottom-left of the window? If so, what does it say as to the number of mods loaded in that area? If Forge is installed correctly, there should be a "Mods" button on that screen which will list all of the loaded mods.

Im surprised by the amount of teachers that use minecraft … Computercraft… :P/>

Stage 3: Might work… but i dont think that is what you are supposed to do

When you have installed forge you run minecraft and the folder generates… Thats how i did it :D/>

Chances are that you didnt install minecraft in the .minecraft folder. Edit your pofile in the minecraft launcher, make sure the game directory thing is checked and try reinstalling forge. After that run it, to check if it works, there should be a mods button on the main menu. If you have that done and working, then you can install ComputerCraft.

Im hoping for you that this is going to work, because my experience with teacher who gives such subjects, are bad. Its the thing I got into coding myself, so I knew the basics. Now I have ± a 9/10, which is really good. If I didnt get into it myself, I probably would have gotten a 5 or something, Ive seen that happen in my class. My teacher was nice and all, but thats it. If I had a question she couldnt answer it, because she cant code. And thats very odd to me, to put someone in a class who cant even do the subject herself.

Actually, I would be interested in your course material. Im bad at german I have to admit, but this will be a great opportunity to learn it proper. I can speak a little german, but when we get in long terms.. yeah.. http://translate.google.de/ (See what I did there? :P/> )

Hey, 1. Can't really help you on that issue. Did not try any modding with 1.6.x. HOWEVER i really like this idea. Small note: i am german myself and i would kinda like to see your teaching material :P/> So, you should maybe sharte it, who knows how useful it will be for others, maybe even other teachers :D/>

This could be a smaller problem than we think. When you are in the Creative inventory, did you click the right arrow near the top to change tab pages? ComputerCraft items are in a tab on another page in the Creative inventory.

if you're still stuck? i found a video tutorial

you may need to setup a new profile in the bottom left on your minecraft launcher
