oh. This sounds like you installed both, a 32bit and a 64bit JVM. Since
windows keeps them separated in those two folders.
java -version should show what is what in case of doubt.
with JNI you have to be extra careful when the architecture changes.

Yes Ernie. I am not getting a JNI error when I attempt to open JAR
from desktop shortcut.
Have to figure out how to reconfigure. There were two folders from
Oracle in the path
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
C:\Program Files\Common Files\Oracle\Java\javapath

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.
Glad you got things going.
I'm guessing that means jdk18 was not installed with the oracle
windows installer. Keep in mind if/when you update to a newer jdk
you may need to fiddle with your path.

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.
Warm regards

And of course, you can use the jdk/jre that NetBeans runs on
to execute
your jar file.
