My system was runig apache 2.0.52+php5.0.2 under Windows Xp without any problem. Today i've decided to upgrade to 5.0.5 but after unzipping the files in the C:\php folder where it was installed de .0.2 version Apache complained about not finding "php5apache2.dll". The message from the command line: Syntax error on line 179 of C:/'...'/Apache2/conf/httpd.conf: Cannot load C:/PHP/php5apache2.dll into server: Especified process not found.
