PHP as CGI to Apache under Win32

Hi there I have downloaded Apache and installed it on a PC. Then I have edited the httpd.conf as mentioned on the different places on the net. Added: ScriptAlias /php/ "E:/PHP3/" AddType application/x-httpd-php3 .php AddType application/x-httpd-php3-source .phps Action application/x-httpd-php3 "/php/php.exe" Additionally I have set the port to 85, since on the same server Ports 80 and 81 are occupied by IIS. Now when I try to open a php file with the browser, this is reacting with a dialog box for downloading the php file... I also tried to comment the two lines "AddTypes..." and write the representations into the file mime.types. Same result. What else must I do to get php work together with Apache? Thanks guys, Rolf.
