Requirements for Java Runtime

The LLS requires that JRE be installed on the machine on which the license server runs. Specifically, the server requires the following:

•

Oracle Java SE 17 or OpenJDK 17.

•

(Only for releases prior to 2017 R2) A 64-bit JRE for a 64-bit license server or a 32-bit JRE for a 32-bit license server. Not adhering to this requirement can cause the license server to fail to start.

•

Windows only: The JAVA_HOME (or JRE_HOME) environment variable on your system set to the path for your default JDK (or JRE) installation

Note:The license server requires only the JRE component. If JRE is your default Java installation, set the JRE_HOME environment variable; if JDK is your default installation, set JAVA_HOME. See the FlexNet Embedded License Server Release Notes for details.
