problem installing vb2005 app from pubish.htm

[Rich]

Hello,

I created a real simple "hello world!" app in vb2005. I also created a
setup app for this app, and it installed on my workstation no problem. Then
I uninstalled the app, and instead published it to my webserver on a win2003
server using the publisher wizard. The publishing went OK, and publish.htm
came up. I click on the Install button, I get the connecting dialog window,
then I get a message that says publisher is unknown do you want to install?
I click yes. Then I get an error message that it could not install the app -
that it couldn't find the files or files were missing. But all the files are
in the webdirectory when I look. Is this a certificate/security issue? Is
there something I need to do in IIS or my virtual directory? Any suggestions
appreciated.

Thanks,
Rich
