WordEngine facilitates best practice corporate visual identity standards in Word. Also WordEngine enables dynamic customization of corporate Word templates and automates formatting according to corporate standards (e.g. logos, colors, translations, headers/footers, and addresses).
WordEngine is a VBA add-in and installation is therefore a bit different from regular VSTO add-ins. A file is placed in Word’s Startup folder which ensures that the software loads when starting the application. WordEngine uses a set of configuration files usually located in %ProgramData%\SkabelonDesign.
