Thanks for your analysis. I will have a look at the issues. Unfortunately the
download feature is not very widely used and therefore I fully believe that
there are some bugs with it.

I personally rather think about extending the download feature slightly instead
of providing a switch to disable downloads globally but keeping them in package XML.

- WPKG might support a flag in a download tag to disable removal after

- WPKG might by default not re-download files which already exist on download

(- WPKG might verify MD5/checksum of downloaded file to check whether download
   was successful; requires some more effort)

This way you could target the download to the %SOFTWARE% share which might be on
local drive or on some non-writeable share. In case of local drive it would
download the file and in case of shared drive (where files already exist) it
will not download it.

For sure the exit code shall be dependent on the install state, not on download
state. I will verify it too.
