I didn't set anything in Settings>Downloads>Steam Library. It contains only the
default C: drive.
When installing a game with the patch applied, Steam shows a drop-down menu and
let me create a new Steam Library on drive D: etc., even though nothing is
added in Settings>Downloads>Steam Library.
This menu is missing with plain Wine.
If I add additional drive letters in the settings they're available indeed.
