Zend Core Administrator Problem

I am quite new to PHP Environment and I've started learning it so I've installed ZendCore. I was trying to change root directory to separate the root from ProgramFiles like inetpub so I change PHP Server Root and localhost:81/ still works but not run the under the folder I created, instead it points at the same old default folder but the probl开发者_如何学JAVAem is ZendCore is not working and it says No input file specified. when I type in localhost:81/ZendCore/

What should I do?

Well ... first of all I'd stop using Zend Core and Start using Zend Server or Zend Server CE unless there is a compelling reason to use Core. Core is Zend's older product and has been replaced by Zend Server.
