Installation problems =(

Hi all... Thought that I should upgrade from PHP4.0 to 4.3 and so I did... But I ran into trouble, as always. when ever I try to load an PHP page I get an alert message saying: "Unknown(): Unable to load dynamic library 'G:\PHP\extensions\php_zlib.dll'" I really do hate php.ini... Why should allways open source and linux/unix things be so complicated? I have php_zlib.dll in the given directory and I've added the line: 'extension=php_zlib.dll' to php.ini since it wasn't there from the start... What do I do? ------------ Now, to prevent from further damage to my setup; I have MySQL 4.0.3-beta and was suggested to upgrade that one too... Can I do this without to much problems? Something I should think about? thanks!!! .bobo
