Hello Alexander and Ernie Thanks for the reply. Was able to get into the System variable of Windows 11 and found that "Path" started with "C:\Program Files (x86)\Common Files\Oracle\Java\javapath". Even though 1.18 was installed and placed in "Path" at the end, the x86 javapath was being picked up and had version 1.8. deleted the string from "Path" and was able to get the app (GabellatteMVPn) running.
Meanwhile got aware of (https://javaalmanac.io/bytecode/versions/). TQ Ernie.
