Welcome to Adobe Forum,
By default the Creative Cloud application will utilize the language settings for your operating system. You can find information on what your current language setting is by review the following documentation:
- Mac OS: OS X: Changing the language shown in menus and dialogs
- Windows 7 and 8: Install or change a display language
If you wish to install the software included in your Creative Cloud Membership to a different language then you will need to make this adjustment in the Creative Cloud application. Full details on how this can be accomplished can be found at Adjust the install language | Creative Cloud applications | CCM.
If after adjusting the language and installing the Adobe Creative applications you discover them to be in trial mode then it is possible your subscription may not include the requested language. You can find more details at Creative Cloud products launch in trial mode on non-English operating systems | CCM, CS6.
Finally you can check if you have an English only or Multi-language membership under you account at http://www.adobe.com/. For more information on how to manage your membership please see Manage your membership | Creative Cloud.
