As a general rule, the license agreement is printed on paper contained in the boxed software. It can also be displayed on the screen during the user`s installation, in which case the license is sometimes called the Click-Wrap license. The client`s inability to verify the license agreement prior to the purchase of the software has led to the absence of legal difficulties in some cases. Recently, publishers have begun encrypting their software packages to prevent the user from installing the software without accepting the license agreement or violating the Digital Millennium Copyright Act (DMCA) and foreign counterparts.
