Solidworks 2014 in English but the help system is in Turkish, how can I have both in English?

I installed Solidworks 2014 on English Windows 7 64-bit, but after installing I figured out that the installation was in Turkish and it did not prompt we for language before installation. After installation somehow I managed to switch the language to English but, the help menu and entries there are still in Turkish. How can I have both the help menu and the UI in English at the same time, does it require a re-installation?
