Visual Building is distributed with 9 languages including English and German. You select the language during the installation.
If you are absolutely sure you selected English during the installation then please try reinstalling with any virus checker temporarily disabled. The virus checker may be preventing the language dlls from being installed.
During the installation process you have the option to select the default language, so be sure you have selected English.
Which ever language you select, you should be able to change the language at any time using the Application menu (Green top left arrow), then select Settings (Einstellungen), then Language ( Sprache) and then the language. This assumes you selected the new ribbon interface at install time. You will then need to restart the application for the change to take effect.
If you can not manually switch language then the problem is likely to be an incomplete installation as described above, usually as the result of an anti-virus program.
If during the reinstall a dialog appears complaining a dll is in use, then select Ignore.
