[SharePoint Error] - An exception of type Microsoft.SharePoint.Upgrade.SPUpgradeException was thrown

Una excepción muy rara y un poco fuera de lugar, dado que no estaba ejecutando algún proceso de migración, como se podría suponer por el nombre y descripción del error.

Failed to create the configuration database.

Por el contrario, estaba alegremente instalando MOSS 2007 SP2 en una máquina virtual.

Después de un rato de buscar en la red, solo se hace referencia en esta entrada de Microsoft Connect. Que menciona que si tienes instalado Office 2010 se puede presentar este problema, y en mi caso así fué. Una vez que desinstale Office 2010 y posteriormente procedí a reintentar la instalación de MOSS 2007, esta se ejecuto sin problemas.

Espero esta información les sea de utilidad.
