adobe pro 11 displays in polish after install

I have done this,

I select the English and everything installs, but after the install, when it opens to run for first time everything appears in Polish

I have Uninstalled and run the clean up util, and restarted the system before trying to reinstall,

I have tried installing as trial version, and it works correctly, but it wont except my product key to convert from trial to full registered program this way
