As per the description, it is a question that KiCad only asks you once, at the first time you start KiCad.
I assume you started KiCad yesterday, just after you installed it, and got that question then.
You probably either accepted the default, or choose one of the other options and clicked [OK]
Try this:
- Start KiCad.
- **File / New Project ** (Makeup a name + Save)
- Start the Schematic Editor.
- Press the a shortcut key (or Schematic Editor / Place / Add Symbol) from the main menu.
This should pop up the Symbol Chooser dialog, which looks like:
If you do see those libraries listed 4xxx, 4xxx_IEEE, etc. then your global library table is OK and you do not have to worry about it and can just continue with the getting started guide.
If no libraries are listed, then you probably made the wrong choice the first time you started the schematic editor. Because you are just starting, the easiest way to fix this is to:
- Exit KiCad.
- Simply delete the configuration directory.
- Restart KiCad.
If the configuration directory is missing, KiCad assumes it is the first time it is started and you get the question to create the symbol library setup again. Then make sure to accept the default, and KiCad creates a new clean configuration.
On my linux box, this directory is in my home folder under ~/.config/kicad. If you use some other OS, then you can just search for the sym-lib-table file itself in one of your user directories.
If you find multiple of these files:
Each project has such a file (the project specific variant) Do not delete those.
There are some other possibilities, such as for example a partial installation of KiCad, and in that case the libraries may not have been installed at all, but I don’t want to make it too complicated for now.
