Minecraft Forums

Hey,

I have some problems when running the portable minecraft i made. At first everything worked perfectly.
I copied .minecraft folder into a new "data" folder on the USB, and the minecraft.exe- icon in a "bin" folder. And then
i made a .bat file with the command:

"set APPDATA=%CD%\data
bin\minecraft.exe"

This all worked fine. But then i got some issues with the school computer i work on (i am a teacher), and the Java on the school computer doesn`t update because of admin issues. So i thought to download a portable java to run minecraft. And here is the problem. I downloaded the jportable launcher but it doesn`t show the .bat file i want to run (minecraftportable.bat). When i chose "show all files" instead of "JAR-files", and then click the .bat file i get an error:
Error: Invalid or corrupt jarfile E:\Minecraft Portable\portableminecraft.bat

What to do? Can someone way smarter than me help me out? I would love for the students I work with to be able to play minecraft as a part of their education.
