Software is governed by a digital license that specifies a certificate that must be present in order for the software (or certain features thereof) to be used. A root authority authorizes a license server to issue certificates that are called for in the digital license for an item of software. The software and the digital license are installed on a machine, and the machine enrolls with the license server to obtain the certificate. When the software is run, an enforcement component evaluates the license to determine what certificate is required, and then evaluates the certificate to determine whether it meets the requirements of a license. If the certificate is invalid, the enforcement component may disable the software, or may disable certain features of the software.
