Hi @ll,
I found this problem just when starting to trial some CC products, but I think it would be the same case if I was already signed for them. Here are the details that I think contribute to the problem.
I am Spanish, living in UK, working with Windows 7 64 in English, my CC account was made from UK, but I changed language preferences to Spanish, and the issue can be reproduced as follows:
1. In a computer with not adobe products installed, get into your CC account and select one product to trial from CC website.
2. It first installs CC app and then you change preferences to Spanish and a different folder than default.
3. Installation process starts, it never asks anything and finally you get that program in English and in the default folder, which obviously was not intended.
4. Uninstall and clean the computer again with Adobe special tool (AdobeCreativeCloudCleanerTool.exe) for not leaving any trace of previous Adobe products installations.
5. Download from a parallel site a multilingual package of the program you are interested. During the installation you can change Language and destination folder and select trial. It will install correctly as per your preferences.
6. Run the program, it will launch the CC app, now you are offered an update, do it, and voila, it is correctly installed in Spanish and the folder of your choice.
7. Now you can select a second program to trial in CC app. It will installs too in Spanish and the folder of your choice.
So in order to get things correctly installed as per your preferences, firstly you must avoid to go into CC web site or CC app as it will do wrong. (????)
