ScriptWorx ships with dictionaries in Danish, Dutch, French, German, Italian, Norwegian, Polish, Russian, Spanish and Swedish - but you have to select the "Custom" or "Complete" setup types during installation to add these languages. However, you may re-run the ScriptWorx Installer, whilst choosing the "Modify" option. By clicking on each entry and changing it to "Install this feature...", you can have the dictionaries installed.

If you already have such dictionaries installed and would like to change them, run the usual spell check option, and choose the "Options" button.

Click on the "Locate Dictionaries" option, and navigate to the directory where ScriptWorx was installed to (this should be shown by default). After navigating to the appropriate directory, click "OK" and the Dictionaries list will fill with all the dictionaries you opted to install. Simply click the check-box next to each dictionary, and this dictionary will be referenced whilst performing a spell check.
