Well, not quite. It tries to create // directory and chokes on it
obviously. My guess is that USERPROFILE is set to a network location
and our code mishandles network paths. If that's the case than I know
how to fix it. It would be great if you could confirm that. Just start
regedit, navigate to:

  HKCU/software/microsoft/windows/currentversion/explorer/shell folders

and tell me what's under Programs key.
