EPM (Excel AddIn) Application Language Parameter

Hi experts, in Excel we can user Application.LanguageSettings.LanguageID(msoLanguageIDUI) to determine the language setting of Excel.

MsoLanguageID Enumeration [Object Library Reference for the 2007 Microsoft Office System]

Does anyone know the parameter for the language setting of EPM AddIn?

It is set in Options --> User Options --> Display : Languages.

I want to read this parameter via VBA.

Kind regards,

Denis
