Notes 8.5.1 German installation but no german mail template

Hi Community

today I installed this package: “IBM Lotus Notes, Domino Designer and Admin 8.5.1 for Windows XP and Vista German (CZ90JDE)” on my XP SP2 German System. Before this I had 8.5.1 english. I did not uninstalled 8.5.1 english before I run the german installation. The installation was successfully and I replaced the mail template design with the local new mail template 8.5 but it’s still english…

any ideas why?

thx a lot
