php5rc1 && (apache2.0.49 || apache 1.3.x) && winxp

Dear list members, I would like to install PHP5 RC1 on winxp with apache. I also installed many times php4 and it works well, but with this one I have problems. I can't install as module nor as cgi, I made all steps as the php install.txt file describes. In module mode, when starts the apache2 server, it gaves the following error message in an allert window: "The requested operation has failed!" When i tried to set as cgi, the server has started, but when i tried to acces php files the browser wrote: "Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request." and so on... The error log file contains the next line: "Premature end of script headers: php.exe" Somebody can help me? Thanks, Dani ps.: Sorry for my bad english.
