Maybe your proxy is not properly handling unexpected User Agent or other 
header strings from wget and setup. 
Have you tried curl - curl often outputs only the HTTP message, and you 
can then add options to generate the correct responses or handling. 
Both curl and wget each support some user specified header addition and 
modification options.

Note that setup seems to require and support only Basic authentication 
and does not process any negotiation, so if your proxy can or does not 
fall back to support Basic authentication, only NTLM, you're hooped!

Have you tried using apt-cyg or another alternate installer?
I could suggest 
    https://github.com/BrianInglis/apt-cyg/raw/wget-non-verbose/apt-cyg

as it has been patched to handle installing dependencies and postinstall 
scripts but does not (yet?) handle upgrades except by manually removing 
and (re-)installing packages.

You may have to do your setup and package downloads via apt-cyg, wget, 
or IE to your packages directories and use setup to do installs from 
there.
