Passolo command line


I start to use the command line interface of Passolo.

I open the dll and create the database but I can't find how to specify the good language code to my new database

I need to set to French France (12 1) 

When I use "Fra" the lpu is create in French (12 0)  not in French (France) 

pslcmd.exe /newproject:CatalogBrowserTool.lpu /addsource:CatalogBrowserTool.dll
pslcmd.exe CatalogBrowserTool.lpu /addlang:"Fra"

I need French(France) because I want to use the /update and my other database the language is 12 1

Thanks for your help
