To update your LANCOM Wireless ePaper Server installation, please download one of the installation packages from the myLANCOM web portal: https://www.lancom-systems.com/downloads/
1) The LANCOM Wireless ePaper Server as of version 1.73 is available as two different installer packages:
Before upgrading to the LANCOM Wireless ePaper Server as of version 1.73, you need determine whether you are operating 32-bit or 64-bit Java on your system.
As of server version 1.91, the free OpenJDK version 11 or higher can be used instead of Oracle Java.
You can find out which Java version you currently have installed on your system from the Java Control Panel.
If you install a 32-bit Java version of the ePaper Server Installer package even though you have 64-bit Java on your system, the installation of the ePaper Server will run smoothly, but the Wireless ePaper Server service will fail to start.
2) Execute the appropriate installation package.
During the update process, the Wireless ePaper Server service is stopped, the update is performed, and the Wireless ePaper Server service restarts.
The update to the Wireless ePaper Server does not cause any change to the configuration.
