What works

Files can be opened and 2D footprints can be displayed. Export to KiCAD also appears to work.

What does not

The built-in STEP file viewer does not work, nor does the STEP file export.


  • Use a 32-bit Wine prefix.
  • Set the emulated Windows version to Windows XP. (Not sure if this is necessary)
  • Install msscript with Winetricks.
  • After installing Ultra Librarian, copy C:\Ultra Librarian\UL.ini from a working installation on Windows before trying to start the program.

What was not tested

I did not test whether the exported KiCAD files were valid (although they appeared to be from a cursory glance in a text editor). I also did not test other EDA package exporting.
