How to remove my educational license from the installed software?

Hello,

I'm trying to create a lab for an Analytics class. I installed Rapid Miner to a Virtual Machine and activated my license there. However, I would like to remove my license from the computer since it is going to be used by another person when I publish this VM. I tried to remove the license, uninstall the software and installing it again but when I reinstall the software it automatically picks up my own license. I would appreciate if you can tell me a way to remove my own license or install a rapid miner which will require new users using the same machine to enter a new license.
