question on installing zend studio?

I really did not want to start a new topic on this but I searched the forum and tried any related solution but nothing helped. Maybe someone with a similar experience can help, I hope.

according to the install wizard,almost press the “next” button in most case,I download zend studio server and safeguard component,want to install zend studio server and client on the same local machine.No error happened during the installation.
after it finished,I run zde(zend development environment),menubar,debug->check debug server connection,
but the response message is “could not establish connection”.

another question: click the icon “zend studio server” on the tooltar,the response is “zend studio server is not properly installed on https://localhost ” .I have reinstall it once but the same result.

I’m sure that php 5.0 and mysql 5.0 have been installed properly.

path: php in d:\php5, mysql in d:\mysql,php.ini in c:\windows\system32,zend in C:\Program Files\Zend(default)
system:winxppro sp2+iis5

I would really appreciate any help you could give! Thanks in advance.
