Difference is that the libraries loaded in my case, but, not all of them AFAIK.
For example, the library for FTDI is not loading. In C:\Program Files\KiCad\share\kicad\library, I can see both the .lib and .dcm files present, but no FTDI part can be found when running Eeschema or parts editor.
I thought that KiCad will automatically include all libraries as long as the folder/directory that contains the libraries is included in the Current search path list… (???)
