Yes.
The licensing is stored in a file called mathpass. There are two folders on every machine where they may be located. One location which works for the entire machine and one location that specific to a login. On Windows Vista, 7, and 8, the mathpass file may be located at:
- C:\ProgramData\Mathematica\Licensing\mathpass
- C:\Users\<user>\AppData\Roaming\Mathematica\Licensing\mathpass
where <user> is your username on the computer.
On Windows XP, the mathpass file may be located at:
- C:\Documents and Settings\All Users\Application Data\Mathematica\Licensing\mathpass
- C:\Documents and Settings\<user>\Application Data\Mathematica\Licensing\mathpass
where <user> is your username on the computer.
On Mac OS X, the mathpass file may be located at:
- /Library/Mathematica/Licensing/mathpass
- ~/Library/Mathematica/Licensing/mathpass
On Linux, the mathpass file may be located at:
- /usr/share/Mathematica/Licensing/mathpass
- ~/.Mathematica/Licensing/mathpass
Install and activate Mathematica on a single machine. After that, you will find the mathpass file in one of the directories mentioned. You can open it with a basic text editor. If you are using MathLM, it will be blank except for and exclamation mark and the sever name.
You can activate other copies of Mathematica by copying this file to other machines in the directories listed. Most likely, you will want to copy them to the first directory listed in each case, which is the directory accessible by anyone using the machine.
If you have any questions about this, you may want to contact Wolfram Technical Support who can answer more about it.
