The on-screen end user license agreement (see
EULA) that is part of the installation of software downloaded to a computer. The term was coined as a replacement for "shrinkwrap." Before applications were routinely downloaded, a written license agreement was included inside or printed on the outside of the box the software came in. It stipulated that opening the box (removing the shrinkwrap) or opening a separate shrinkwrapped set of discs was explicit acceptance of the agreement.
There have been several court cases involving the clickwrapped license, and outcomes have favored both the software publisher and the customer.
