VS 2003 Pro running on XP

I have created a setup and deploy project for my project.  I have added
'Content files', 'Localization resources', and 'Primary output'. I get
warnings when I build the project:

WARNING: Two or more objects have the same target location
('[targetdir]\bin\webApp.dll')
WARNING: Two or more objects have the same target location
('[targetdir]\bin\webApp.dll')

After building, when I look at the files system menu under my setup
project, 2 of the 3 things I added are underlined in red.  The ones are
Content and Primary output.  I looked and both of them reference
copying the webApp dll in the output tab.  I have the same setup on my
desktop at work and it works great.  Its been that way for about a year
now, and I had the same problem back then but I don't remember what I
did to fix it.

When I load what the build gives me, there is not content files or
dll's in the install.

I also get an error when I try to install that says:
the folder path '?' contains an invalid character

I've never seen this before.
Any ideas?
