The Windows filesystem has an unfortunate property that deleting files can
signal permissions errors when someone else has the file open, IIUC. This
also generalizes to deleting directories when someone else still has a file
in the directory open.

John: do you have a stacktrace for those errors, by chance?

The GUI tells you how it calls install when you click on the "show details"
button.

It does "--deps search-auto" by default, I believe.
