I would like confirmation if the flexnet agent has any type of dependency with Java?
We need to upgrade our version of java that has been deployed to all machines and need to understand if we upgrade will it cause any issues to the flexnet agent?
If the agent had such a dependency, you would find out about it in the prerequisites: https://docs.flexera.com/FlexNetManagerSuite2020R2/EN/SysReq/index.html#FNMS_sys_req/RN_sys_req_prer...
Also, from my personal experience, I can tell you that the FNMS agent will install on a clean Windows machine.
Markward and Kirk are correct if you're asking in context of the FlexNet inventory agent included with FNMS, but if you're asking in context of the FNMEA agent (being deployed on license servers) then there are Java components included.
