1. In the options menu it's already configured to English language:
2. I use entire method filter for exsample. On the first page of the filter wizzard it shows English configuration too:
In the script objects and models types names are in Russian language. I have installed English language for ARIS only, and I have not installed Russian language.
As I found the method language in scripts comes from server. So I can't change it by the client settings. I've reinstalled server and have chosen English version only. Now attribute type names shown only in english.
