Under Hilfe is sprache with two choices; Automatische and Deutsche. I un-check Deutsch, and restart the program and it still starts in Deutsch. How can I change it to English? Ver. 22.2.0.53 (DP3)
What is the language of your Windows Operating System? My suspicion is that whatever language is the "core" for your computer is the one that ACL will default to.
I'm running version 24.0.1.16 and the language options for me are "Automatic", "Deutsch" or "English", with the latter ticked.
