During the Evaluation period of Statgraphics 19, you may switch between languages by selecting *Edit - Preferences* from the main STATGRAPHICS Centurion menu. Click on the *Language* tab and select the language you wish to use. You may select different languages for the user interface and for the output. Once the evaluation period is over, the languages you have access to will depend on the license that you purchase. Access to more than one language requires that you purchase a license for either the Bilingual Edition or the Multilingual Edition.

**Important note:** When installing a new build, do not uninstall the previous build. The new build will replace the previous build and will not require reactivation.
