George,
?
Your log shows a folder named "C:\Users\TEMP.WINDOWS-T0ML932.003\JMRI" that Dave refers to as a "sandbox" and this suggests that some antivirus might have interfered with either the installation of the distributed folder or the execution of the program app.??
?
Since you stated that your club does not have an internet service connection, the antivirus suggestion might be a misleading rabbit hole, but checking for that possibility could provide some new clues. ?Some other program running or or some setting on your computer has forced that decision at run time. ?
?
Our club does not have an internet connection either.? We run PanelPro 5.10 on a Windows10 computer for the layout and DecoderPro 5.11.3 on a windows 7 computer for our workbench.? Both computers using Zulu Java version 17 with only a few hiccups during the installation process.? ?The layout computer is hardwired to the WiFi router.? There is no antivirus running on either machine.??
?
The layout and the workbench both use Digitrax DCS 210 connections, but that is extraneous to this puzzle.
?
Updates are carried in on memory sticks but one member has been advocating using a cellphone hotspot connection.? We have not tried that.
