env -
Tomcat 6.0
(PHP Version 5.2.17), mysql - 5.5.19, zencart v 139h

When starting the install using url
....zc_install/index.php?main_page=inspect&debug=ON

I am getting following displayed -

Webserver =

HTTP Host =

Path_Translated = (SCRIPT_FILENAME)

Real Path = C:\tomcat\webapps\forphp\merigift

PHP O/S = WINNT

PHP API Mode = java_servlet

PHP Max Execution Time per page = 30

Register Globals = OFF

MySQL Support = ON

# MySQL Version = 5.5.19 Click here for more info

PHP Version = 5.2.17

PHP Safe Mode = OFF

Click on more info and it give error_code=90 but no details in pop up window.

if i run ....zc_install/index.php
Blank page comes.

PHP set up is working fine as i am able to run phpinfo and correct php.ini is picked , also extension dlls are uncommented in php.ini.

Also have PHP and PHP/ext diretories in the PATH.

Any idea what i am missing here?

Thanks in Advance.

Here is what i have in the Cache directory, if it helps.
