Problema AppServ en Windows 2000 server

[aalleexx81]

Hola a todos, tengo un problema en mi servidor, no consigo hacer andar apache.
No sé si es el lugar idóneo para realizar esta pregunta.

He instalado el paquete Appserv 2.5.10 y me reporta el siguiente error:

La instrucción en "0x0068c0ad" hace referencia a la memoria en "0x01102000". La memoria no se puede "written".
Haga click en Aceptar para finalizar este proceso.
Haga click en CANCELAR para depurar el programa.

Os dejo el contenido del fichero error.log del programa:

Estoy un poco desesperado, he reinstalado varias veces y nada.
Espero vuestra ayuda.
Gracias a todos.
