You can't,

when you install Maya, you need to submit your computers IP address to Autodesk who then customise the license to that machine. When my old computer died I had to get them to transfer the license over to my new one before it would work. I believe that you can get floating licenses which I think work with a dongle, that way you can use multiple machines but unless you requested that when you purchased you don't get it.

Take it easy,
