Some network install issues

1: When I build my Deployment, I have a chance to define a 'default
profile'. However, I don't get to point this at an ARG file, so this default
profile uses default settings, no office standard mappings, nothing. I might
as well call it 'garbage' as it is useless and I will delete it. Or am I
doing something wrong, and I can make this 'default profile' have some
meaning?

1.5: Or am I supposed to use the name, then use the ARG renamed REG to push
the settings for that profile. Allong the same lines, I thought you could
supply an ARG file in a shortcut, and Acad would load that ARG file if the
profile didn't exist. Is this no longer available?

2: I have configured R2004 to look at a local text file for upgrades, but
when I try to run the install for Tool Palettes Extension with the /P
switch, it actually looks for an install of Acad. I thought the whole point
of the switch was to have it unpack the files to a designated folder and
make a text file with the information Acad needs. The help I have found even
says that if you don't use the /P switch the extension will actually
install, suggesting that with it it won't. Again, am I doing something
wrong, or misunderstanding how this is supposed to work.

3: And lastly, I can't seem to get %USERNAME% to work as part of the Plot
Style path, but it works fine for the general path. Can anyone verify that
indeed environment variables are not enabled for anything but the general
path? I would be sad, but I would also give up and address the pathing
manually at each instal.

Thanks,
