I just installed PHP on my XP machine. I followed the advice and installed it at c:\php\ and not in the program files directory. I went into IIS and added the mapping for .php files to c:\php\php5isapi.dll. I then created a test page and when I try to browse it, I get an error that says Specified Module Can Not be Found. Does anyone have any idea what setting I need to change to get this to work?
