On each Oracle Smart View for Office client machine, the following locale settings should match:
Smart View language option
Microsoft Office language
Windows Regional Settings
Windows operating system
Running Smart View in a language other than the language of the machine's Windows operating system, system locale, or Office language, may result in incorrect data being returned. For example, if the Windows operating system, system locale, and Office language are English, and you run Smart View in Russian, reports or chart data may display incorrectly.
