If you want to type German only, set keyboard mode to "2. Combine On Request (English)" and charset to "4. Unicode". Note that the smart Viet Option Page is no longer active because WinVNKey knows you will not type any Vietnamese text.

Click on the word French to display a list of all German characters and how to type them in. If any entry is listed in red color, it means the corresponding character is not available in the character set you have chosen. You certainly see a lot of them in red if the character set is VISCII, for example. You must see no red if you have selected Unicode or Windows codepage 1252. If you prefer a different way to type in German characters, you can redefine by clicking on the "Edit File" button.
