why to hell German language?
My windows in 64bits Windows 10 enterprise Polish but whatever I try XD downloaded and reinstalled pop-ups in German. Ok I can understand XD may be not in Polish but at least English - not this German.... :(
Wondering if maybe some setting in your system has German as default language? Possibly the Creative Cloud desktop app. You can check/change by opening preferences (three dots to right of your name in the top right and selecting ’Preferences’> Creative Cloud).
Hope this helps!

I have set the language to english in CC-preferences, but XD still uses the system-language of my (Mac) OS...
Changing the OS-language is not an option, because it has many unwanted side-effects.
