I am trying to set up Zenphoto on a Windows 2003 server running IIS 6. I installed and configured PHP on this server using the tutorial at http://peterguy.com/php/install_IIS6.html
When I run the test.php script from that website, everything is fine. However, when I attempt to run setup.php, I only get a prompt to download it. All of my setup on the server looks fine; the application configuration is mapped to handle .php, the Zenphoto folder is inheriting these permissions, etc. and, as I mentioned, the test.php script runs fine.
I am a total PHP noob and have no clue where the problem could be; lots of research hasn't brought up anything that helped. Any ideas?
