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.
