If you happen to use the Wiznet220UI modules like me, you may have noticed that the configuration tool stopped working in Windows 11. As it starts up, there is a strange error message (it was probably originally written in Chinese and my OS does not know how to display that properly).

You can fix this by right-clicking the tool shortcut, choosing Open in folder, then right-clicking the shortcut, selecting Properties and then selecting the Compatibility tab. In my case, I set the compatibility to Windows 8 and it started up normally. But it did not find any modules when I clicked Search. As I closed the files, Windows asked me if compatibility settings worked. I answered No and it set some different compatibility settings that solved all the problems.

It’s not rocket science, but it works 🙂

It is also a good reminder that most software tools will simply stop working in about a decade or so, unless the author is really diligent about updating them regularly. This will usually not matter for computer software like image and document editors, but it becomes very relevant when you are, for example, building a smart home; you probably don’t want to strip all the hardware out every 10 years or so just because the configuration software is out of date.
