by default, the /download operation will actually work fine with the default/example configuration.xml (the one which has EVERYTHING commented)
I just tried this again, i.e., I have a folder:
c:\users\Don\Downloads\ODT
In that folder, is:
setup.exe (the ODT)
configuration.xml (with only the <Configuration> and </Configuration> elements are active, everything else is in there but is commented out with <! )
This downloaded the 32bit C2R into the current folder structure:
.\Office\
.\Office\Data\<files>
.\Office\Data\15.0.4675.1003\<files>
There is a logfile for the ODT, created in %temp%.
The filename looks like this: <computername-YYYYMMDD-HHMMa.log
Mine shows lots of stuff, including:

Whilst the ODT is downloading the C2R files (it uses BITS, so you can't see much happening), the setup.exe will actually not seem to be doing anything, it doesn't visibly show progress, it almost seems like the process has hung.
It will eventually just complete, without any fanfare or trumpets.
