Install to localhost

Well, I hope you're enjoying the challenge and not under any big deadline!
Do you have a PHP-based SQL admin tool like Adminer or PHPMyAdmin? Can you do http://localhost:122/phpmyadmin and it works?
If it doesn't, I'd say it has something to do with either IIS or that you're using a port number, though why shouldn't you be able to do that? As for IIS, are you able not to run it or do you have something else that requires IIS?

Yes, I can run http://localhost:122/phpmyadmin without issue, or most any page I make unless it is the CI or another DB type page.  All of my other websites are using IIS and why I need to keep that running for their development (I have other php sites running under IIS, but no db activity for testing), and needed to put this on another port, 122. (and, of course, the client would like this sooner than later, as always!)
