Problems with instalation

Dear madames and sirs, I have problem with a php interpreter on my computer, running on Windows 98, using Personal web server for testing and developing purposes, I have PHP 4.3. 1 Everytime i try to access to a php file I get a "Security Alert" - the PHP cannot be accessed directly. I found solution of this trouble in install.txt and set up cgi_force_redirect = 0. But I´m afraid this action did not help and the same problem takes still. I used windows instaler and php.ini is located in C:\Windows directory. Please could you help me and send instruction to make PWS works properly with php files. ( In W2k enviroment php works without problems) Thank you for your attention, yours sincerely Aleš Tumpach, Czech republic
