For some reason, calling `AssocQueryStringW` on Windows Home returns error
code 122, "The data area passed to a system call is too small", even when
the data area is large enough. Furthermore, the API actually describes that
in such cases `S_FALSE` is supposed to be returned, with `*pcchOut` set to
the required size. Because of this apparent violation of the documentation,
and because it just works, Flamenco now ignores this particular error and
just returns the obtained string.
Blender Finder now understands that directory paths should be suffixed
with `blender` (Linux, macOS) or `blender.exe` (Windows).
Giving the Setup Assistant a path like `C:\Program files\Blender
Foundation\Blender 3.2` will now just work. This is considerably simpler
for many users, as copy-pasting a directory from a file explorer is
simpler than obtaining/typing the path to the executable.
