I have a German operating system which is bad enough and Photoshop is also German. My language preferance is English this has also been changed in the Creative Cloud App.
How can I change the Photoshop language,
Oops I feel silly as it was dead easy
Edit -> Preferences -> Interface
Select Interface in the list to the right.#
Select the UI language (I have German and English to choose from, no idea how to get others).
Restart Photoshop and the language should have changed,
