Do you not get the option to change the language of the package when you are installing it? Up to now all Adobe products came with multi-language installers and the default was always the local settings (language, time zones etc etc) but users were able to change the language.
Now the above was true for all desktop/perpetual versions but things might have changed in DW CC versions which I don't use nor have I tried it yet.
Moving your question to a more appropriate forum. The experts here are better placed to help you.
Please follow the kb: http://helpx.adobe.com/creative-cloud/kb/change-installed-language.html to change language of CC apps.
Please download CC desktop from the link provided: https://creative.adobe.com/products/creative-cloud, change language from preferences and install the software in English.
