Hola,Bueno despues de volverme loco tratando de solucionar, el porque a la hora de instalar Mucore por mas que haya puesto todos los datos bien en el config.php me seguia largando el error "Connection with MuOnline Database Failed - Fix this" Encontre este archivo i decidi subirlo

Solucion: pegar y reemplazar este DLL en la carpeta Xampp/php/ y Apache/Bin/
En el caso de usar Xampp
reinicial Xampp Y Listo.

ntwdblib.DLL - 4shared.com - Recuerden que para poder poner bien todo cuando estan instalando la web en este paso :

http://localhost/install/install.php?step=step_1

Cambien el _1 por _2 que quede asi:
http://localhost/install/install.php?step=step_2



Configuran el Config.php asi:
