osscommerce y servidor windows

[conkis]

Hola, tengo un pequeño porblema con osscommerce y un servidor windows (hasta para esto da por culo) y es que no puedo cambiar los permisos de los archivos y me da erroes al intentar abrir o modificar el archivo include/configure.php en la instalacion.
aun modificandolo a mano me funciona

errores en la instalacion:
