Operating Environment Language Requirements
Agent Desktop and Supervisor Desktop can be installed on machines running localized operating 
systems. For a list of supported languages, see 
In a non-English language environment, it is necessary to install Desktop Administrator on a 
machine with a localized operating system so that Call/Chat messages, tooltips, enterprise data 
names, and other communications within the contact center are in the local language.
NOTE:  When you change the language for a contact center, the data in LDAP is 
completely wiped out. As a result, CAD client desktops must be configured again 
in Desktop Administrator. In other instances when you run the Cisco Unified CCX 
Desktop Client Configuration tool, the data in LDAP is preserved. See 
 for more information.
A CAD deployment cannot support more than one localized language. All agents and supervisors 
must use the same language—there cannot be some agents and supervisors using one language 
and other agents and supervisors using another language.
