Introduction
It is highly recommended that your organization use the latest version of the FlexNet License Server (11.19.6.0 or later). If you are using an older version of the software, please download the latest version of the FlexNet License Server Installer.
Note: All FlexNet Publisher versions prior to 11.17.1 are officially past end-of-life and no longer supported by Revenera. See Revenera's End-of-Life Policy and Notices for details. Running an unsupported version means no further security patches will be released for it, regardless of what issues are discovered.
Older, retired versions of FlexNet License Server carry known security vulnerabilities that have been publicly disclosed and are no longer being patched. The table below lists the vulnerabilities associated with each version.
