After downloading, I too tried to open the TaxParcelEditingMap template, from my Windows Explorer, going first into TaxParcelDesktopInstall, where the template is located. I got an error stating "ArcGIS 9.3 or higher including the .Net Support Feature is required to run this application."
We are running ArcGIS 10. I haven't found a solution yet, and I'm not sure right now if we have the .Net Support Feature installed with our ArcGIS Desktop.
