PHP 5 Beta 1 and IIS

Hello there! Just wanted to know if anyone succeeded in installing the latest PHP 5 Beta 1 under IIS (5 or 6) I tried : - ISAPI configuration : the loading of "php4isapi.dll" by W3SVC failed (I put php4ts.dll and php.ini in %systemdir%) - CGI/EXE configuration : I get the following (I put "cgi.force_redirect = 0" in php.ini) : >> CGI Error >> The specified CGI application misbehaved by not returning >> a complete set of HTTP headers. The headers it did return are: Any idea? PHP5 "structure" seems to be equivalent to the one of PHP4 (DLLs are always named php4___) so I'm wondering if there's a bug in IIS support rather than a new way of installing it compared to PHP4. Thanks in advance for your suggestions den
