Well, I got it installed but it requires the publishing infrastructure to exist in the site collection hosting the template and the parent site needs the publishing feature activated. This might be the default for your MOSS Intranet site but WSSDemo.com was based on the Collaboration only template.
The template also requires the enterprise edition of MOSS because of extensive use of the BDC and Excel Services (this is not mentioned on the download page.
After activating the required features there were some adverse side effects.
- Extra Home tab in the navigation (I should be able to delete this)
- Tab highlighting for current site not working
- DVWP in the master page on the site in which I activated the publishing feature now gives an error http://www.wssdemo.com/template
The only thing I haven't been able to configure in the Sales template is the Excel Service ODC file because you need to create this from Excel which I can't do over the internet at the moment (another problem to fix).
Time for some sleep...
