Problem statement : lmadmin installation as a service fails when Jre 16 or newer is used .
Error: The installation of FlexNet Publisher License Server Manager is finished, but some errors occurred during the install. Please see the installation log for details
Reason : lmadmin uses services.jar which internally uses sun classes not supported by Java 16 onwards .lmadmin has a dependency on InstallAnywhere where the issue is reproducible .
Note : Kindly use JRE 1.6 until 16 (for OS X: JRE 1.7 until 16) till the problem is resolved .
