Yes please! Please let us change the language of the Adobe Creative Cloud app itself.
Concrete case: I have a Windows environment in Portuguese, from Portugal. Adobe Creative Cloud shows the UI in Brazilian Portuguese, which is very different. Not to mention there are syntax and grammar errors here and there. So I would rather see the UI in English. I've set all my Adobe apps to show the UI in English.
I know that changing Windows language will make Adobe CC to show in English, but that is not an option. I want my operating system in my language because it actually has a correct language, grammar and syntax everywhere and the overall UI is pleasant to use. But to see Adobe CC UI in Brazilian language and assuming that is Portuguese, is a big NO for me.
Please let users change the language of the app itself! The programming is already there, its just an option!
anyway, you can try to change the website language and then download the installer. i'm not sure that will work, but it might (or might not) be worth trying.
