Thank you, Vidar, the problem is solved with your solution. I went to the page you mentioned, and the first thing I saw was their Note about MS Visual Studio (not VS Code) and I then saw that there is a copy of Visual Studio on this Windows 11 laptop that had not been updated in a long time. So, step 1 was to update it. And that solved the issue. I guess I don't know why the installation/updating/uninstalling/reinstalling of nRF Connect for Desktop did not catch the missing Microsoft C++ Redistributable, but I won't worry about that, now.

Hi Burt,

Thanks for the clarification. From what I can find, this error indicates that a DLL cannot be loaded, which can happen if the required Microsoft C++ Redistributable is not installed. Could you try installing /re-installing this and see if helps.

This problem is happening on a Windows 11 machine. It does not happen on at least one of my Windows 10 machines. I uninstalled nRF Connect for Desktop and reinstalled it, on Windows 11; that did not help.
