MultiCraft has been discontinued
I've stopped working on this project and started a new project just like it that works on Windows, Mac, and Linux. You can check it out here
What is MultiCraft?
MultiCraft is an external tool for Minecraft that allows you to have multiple installations of Minecraft on a single computer!
This means you can have as many separate instances of Minecraft as you want, each with it's own mods, saves, etc. It's all made easy by MultiCraft which stores and manages each one so all you have to worry about is double clicking their icons.
In addition, MultiCraft makes installing mods a one step process. All you have to do is drag the files onto an icon and it adds them to that instance's minecraft.jar and deletes META-INF for you!

How to install MultiCraft
Installing MultiCraft is very simple.
Frist, make a folder for it. MultiCraft will download and create files in whatever folder you put it in, so it's best to give it it's own folder.
Download MultiCraft from the link below.
Drag the file you downloaded into the folder you made and run it.
Remember, MultiCraft is not meant to be installed on the desktop. Instead, you should put it in it's own folder and make a link to it on your desktop.
Download Be sure to read the instructions! Changelog Report bugs to [email protected] or post them on this thread. Remember to read this before reporting a bug. (From now on, if you post a really long error message on this thread, please spoiler it to avoid cluttering up the thread. Thanks)
Installing mods with MultiCraft
Not only does MultiCraft make managing multiple Minecraft installations easier, it also makes mods easier to install.
Step one, take all the files you want to add to minecraft.jar and drag them onto the icon of the instance where you want to install them.
There's no step two.
Here's a video of me installing about 20-30 mods in 3 minutes.
You can also install mods by dragging their zip files onto an icon. When you drag a zip file onto an icon, MultiCraft will add the contents of the zip file to minecraft.jar instead of the zip file itself.
How to manually update
As of version 1.3.3, MultiCraft will download and install updates automatically. However, if for some unknown reason you want to install your updates manually, doing so is very simple.
Download the latest version of MultiCraft from the download link above.
Open your existing MultiCraft folder and replace your old MultiCraft with the one you downloaded.
You're done. Enjoy using the latest version of MultiCraft.
How to ask for help / Report a problem
There are many ways to do this. One of the easiest is to post on this thread, but you can also send an email to [email protected]. Before you do either of these, however, there are some guidelines to follow.
Information is important. If you just say "Y IT NO WORK!?!?!", I can't really help you, however if you actually tell me what's wrong, then I might be able to help. It's generally a good idea to include things such as: error messages, stack traces, what you were doing when the problem occurred, what version of .net you have, what OS you're using, whether it's 64 bit or 32 bit, what version of Java you have installed, what version of MultiCraft you're using, etc.
Make sure you're using the latest version. Many bugs from older versions may not exist in newer versions. Make sure you're using the latest version of the program to avoid the embarrassment of posting a bug that's already been fixed. (Remember, the changelog isn't always up to date )
Use common sense. I don't think I really need to explain this one. It's pretty straightforward.
Stupid questions will receive stupid answers. Again, pretty straightforward.
Read the common problems section before posting. If you don't find your solution there, then you can ask for help.
If you're going to paste a long error message, please use the following format:
[spoiler]Insert error message here[/spoiler]
Just replace the "insert error message here" part with the error message. Common Problems
MultiCraft crashes on start or when I click update
This is a bug with the update system in version 1.3.3. It was fixed in version 1.3.3.3. Then happened again in 1.3.4.0... To fix it, please update to the latest version manually.
Norton File Insight says MultiCraft is a virus
I assure you, it's not. Norton File Insight seems to be giving false positives. You can read this Wikipedia article about it to learn more.
I've also posted multiple virus scans in the past. http://www.virustota...82ef-1324314723
Disclaimer
MultiCraft does backup minecraft.jar, but it does not back up your saves. I am not responsible for any loss of saves / worlds or anything of the sort. It is your responsibility to back up your saves just in case something goes wrong. I do not guarantee that it won't. I will not be held responsible for any damage to your saves or anything else caused by using this program. That said, it is extremely unlikely that MultiCraft would cause any damage to your saves or your Minecraft installations.

All icons (except the main MultiCraft icon) are from the Open Icon Library. You can get it here.
MultiCraft uses DotNetZip for installing mods. You can get it here.
Would you be able to add a option to allocate more RAM to the instances or to the launcher in general? I have 16GB of DDR3 and I need a bit more than the standard 500-1000MB in order to run high resolution texture packs. Other than that great program.
Also it would be very useful to be able to choose whether to launch 64-bit Java or 32-bit Java.
With those additions this utility would be near perfect :biggrin.gif:

There isn't really much to see but I guess I could add one or two.
What DropBox folder?
The only things that should be in the instance's folder are .minecraft and instance.xml... What's in the dropbox folder?
Can you post a screenshot?
This is what it should look like:
I just upload it to tinypic.com and use the insert image button on the forums. Not sure if there's a better way XD
Type [ spoiler ]Content[ / spoiler ] without the spaces
EDIT# I do have drop box btw
That's probably why then lol
Although I don't know why it would put a folder there... O_o
Why i asked was i thout the programe stole my user/pass O.O\
