At the time of purchase, all users are presented with this text at the checkout screen.
"NOTICE: All sales are final and there are no refunds on software purchases. All hardware is shipped with a Limited Warranty. Please review our website for details: http://www.presonus.com/products.

However, you are able to sell you software to another user and transfer it to their account by submitting a license transfer request. More information on that process may be found HERE
