setup wizard not launching

The following information is required to get an answer:
Get this information from the PHP diagnostic (in the configuration wizard).

Gallery version: 1.5.10
Apache version: 2.2
PHP version (don't just say PHP 4, please): installed from php-5.3.2-Win32-VC6-x86.msi
Graphics Toolkit: installed from netpbm-10.35.74.tgz
Operating system: windows XP SP3
Web browser/version (if applicable): chrome 4.1.249.1064 unknown (45376)

when i open the setup URL http://localhost/gallery-1.5.10/gallery-1.5.10/setup/ as specified in install instructions the setup wizard does not execute instead i get the setup directory content below.

then most of the php files I will click on will produce nothing or numerous errors like this.....

errors when selecting http://localhost/gallery-1.5.10/gallery-1.5.10/setup/session_test.php

Warning: date_default_timezone_get() [function.date-default-timezone-get]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

PS: attached files php.ini and httpd.conf

Hello thank you for your advide. I want to use Gallery1 because it does not require a database that I don't need for my project. So which level of PHP has been tested with Gallery 1.5.10?

Bob
