By default all PureVisionXP text is in English.
There are 2 additional slots reserved for German and French. When additional (.Lang) language files are available you can download and place then in the main PureVisionXP folder. This will allow you to select the available language of your choice to better understand the various text within PureVisionXP.
You can also use PureTrans (included with PureVision) to create your own language file if one does not currently exist.
