The two files within the zip file are "resource.deu" and "deu"

"Resource.deu" must be placed at the root level of the RIP installation (Xitron/Navigator 10.1r2 for example). 

"Deu" must be placed into  /<RIP>/messages/xitron,  (C://Navigator 10.1r2/messages/xitron, for example).

You may need to work with your sales representative or support contact if you have trouble enabling this via LDK licensing.
