--- Comment #4 from Brad Anderson <eco at gnuk.net> ---
Added Rainer and Martin on the CC. Assuming it's the same bug you hit, it seems
you can reproduce by going through the uninstaller and installer as quickly as
possible. The uninstaller "finishes" almost instantly once it gets to the RMDir
/r part which makes me think it's doing the deletions asynchronously and the
new files being added by the installer are subject to the delete. Very ugly
bug.

One quick fix might be to rename the C:\D folder prior to deleting it. I'm
unfortunately too busy at the moment to try to fix this myself but might be
able to look in a couple weeks.
