Help with Php4.06 installation

Hello, I am trying to install php4.06 on windows98 machine with PWS and I ran into difficulties. I installed the php using the binary php4.06 installer from the php website, in the directory c:/PHP. I made all the necessary adjustments (I think) as described in the online documentation. The whole php4.06 binary package was extracted in the c:/PHP. I've copied the php.ini in the windows directory and made the changes (suppose those are correct) and the php4inst.dll in the /system directory. I've checked the permissions and those are correct. I also ran php.exe -i and the executable appaers to run. Still, when I try to run a simple php scripts, the output is the CGI Error:"The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:" the path I try to access through Netscape is: http://ppp/scripts/database/test.php I'd like to ask your help in installing and setting up correctly the PHP. Thanks for your help. Mihai
