+- Closing a library releases its lock explicitly (issue #680). On Linux and macOS the lock used to go with the file

   chose) and ends on a page saying it was installed, with a "Launch LightCraft" box. It used to finish without a word,
   so a successful install looked like nothing had happened (issues #18, #399). Silent installs (`/qn`, `/passive`)
