I can't find a file in the new php...

This was not a problem with the previous version of php, but when I downloaded the new version, and when I tried to install is on my web server that I have on my computer, I can't seem to find the php executable file (php.exe), which I need to know where it is in order to make it work correctly. The server which I have is Abyss Web Server. It worked fine before, but the file must not be in the main folder, or it is renamed. Either way, I would appreciate knowing where that file is located at. Thanks, J. Meteo
