Dear HydroNumerics Team,
I am writing to kindly ask for your assistance regarding an issue I have encountered when launching the software on Windows.
When starting HydroHub Lite (version 1.1.1, Build 1558), the application crashes shortly after launch. The following error is reported in the log:
14:52:00 INFO:
Version: 1.1.1
Build Number: 1558
Built: 2025-12-16 06:50:18
User: my627599
14:52:13 ERROR: UNCAUGHT EXCEPTION
Cannot invoke "java.awt.Image.getWidth(java.awt.image.ImageObserver)" because "" is null
Class: sun.awt.shell.Win32ShellFolder2$MultiResolutionIconImage
Method: getResolutionVariant
The error occurs immediately after startup and does not appear to be related to any model configuration or input data.
As I am still learning to use HydroHub Lite, I was wondering if you could please advise on the following:
the recommended Java version or runtime environment for HydroHub Lite on Windows, or
whether this is a known issue and if there are any suggested workarounds.
I would greatly appreciate any guidance or suggestions you could provide. Thank you very much for your time and support.
Kind regards,
My Nguyen
