You can get the same version we purchased for departmental use installed on your own PC, for a cost of 40$s. We have set up this for Auburn ECE students.
Visit the student purchase site if you wish to do so.
Search for the latest version of NI ELVISmx in NI web site. Install that even if you do not have ELVIS. This will provide drivers necessary for Multisim to simulate a partial list of the Elvis board’s functionalities.
