LanguageSettings in project?

Greetings,

the office application word, excel and powerpoint have the method "LanguageSettings", where I can see the installed product language.

ObjWordApp.LanguageSettings.LanguageID(Microsoft.Office.Core.MsoAppLanguageID.msoLanguageIDUI).ToString
ObjExcelApp.LanguageSettings.LanguageID(Microsoft.Office.Core.MsoAppLanguageID.msoLanguageIDUI).ToString
ObjPowerpoint.LanguageSettings.LanguageID(Microsoft.Office.Core.MsoAppLanguageID.msoLanguageIDUI).ToString

Only project has not this method.

How can I see the installed language of the ms-project client?

Thank you!
