Deployment/installation

[dangerdoc]

Hello,
I am programming a game, and I want it to self download the files. This is the process I would like for installation:
Download Startup Window
Run Startup Window
Startup Window downloads and stores the files needed onto computer
Startup Window Runs main jar for game
Startup window closes
Game starts

Is there a way to put .jars, textures and native jars in a place that the program will load, and that will work on different operating systems? I basically want a small .jar, or .exe etc. that you can run from the desktop, which downloads the files onto the computer, and runs them. It would be a small program that starts the game. An example is Minecraft. How can you do this?

Thanks,

Use GetDown.

Does GetDown run the program from the desktop?I would like a small .exe with an icon that runs GetDown, and then my .jar . I know it is possible, but how do you make a .exe that knows where the program files are, even on different OS's so it can run them? Are you supposed to use GetDown in combination with another tool?
