Attribute m_pOwner must have a value

Hi,

I am installing sneak WAS and i have this message in the second step "SAP System installation":

""TRACE

setting ACL of node 'C:/Archivos de programa/sapinst_instdir/j2ee-sneak-preview/install'

to '(SYSTEM,GROUP,=rwx) (SAP_LocalAdmin,GROUP,=rwx) (Administradores,GROUP,=rwx)

(Usuarios,GROUP,=rx) (Usuarios avanzados,GROUP,=rwx)' with mode 'INHERITFILES|INHERITDIRECTORIES'

ERROR 2004-09-14 12:05:48

FSH-00003 Attribute m_pOwner must have a value when calling function CSyACLImpl::getOwner().""

Anyone knows a possible solution?.

Thanks in advance.
