Hi
What might have happened is that you have over written your English run time engine with the German one. You could try uninstalling your runtime engine then reinstalling it.
Has it effected all the langue setting in LabVIEW or just your executables regardless on whether they where written in LabVIEW (German) or LabVIEW (English.)
LabVIEW Run-time Engine Version 8.0 for Windows 2000/XP
Regarding running LabVIEW (German) written programs in English you can localize your applications
If you can post you VI I will have a look at it here, see what it effects and see the best way to reverse it.
