Issue:
The Worx Plugins load, but he palettes do not work properly or look incorrect.
Causes:
Autodesk changed how their API works in AutoCAD 2025 and ECE needed to migrate our code. This means, our old versions will not work in the newer versions of AutoCAD. ECE has migrated our code over, but to allow users to run the Worx plugins in AutoCAD 2024 and older, as well as, in AutoCAD 2025 and newer, we have to ship two versions of the plugins. The files are all in the same installer, we now have different dlls files to load depending on the version of AutoCAD that you are running.

Solution:
You will need to upgrade to a minimum of version 2024.96.1400.0 and then load the appropriate Worx Plugin files.
To determine which file to load see this article: Loading the Worx Plugins
Notes:
This will continue until we no longer support the older versions of AutoCAD. For reference, ECE only supports the current version of AutoCAD and three prior versions. For example AutoCAD 2026 + 2025, 2024, & 2023.
