Event Error ID 604 Esent XP SP3

I noticed during the install of Comodo Internet Security with just the firewall that there were several event errors. All the same.

Event Type Error
Event Source ESENT
Event Catagory General
Event ID 604


Svchost (1068) Locale ID 0x00000409 (English (United States) English) is either invalid or not installed on this machine.

Does anyone know what this means?
