How do I set the language for the display of the RetailVista POS user interface?

In the .Config file that belongs to the started RetailVIsta POS (Touch or Scan) application, there is a segment 'AppSettings'. In this segment, there is a field called AppUlCulture or it can be created. However, it is recommended not to define the AppUiCulture field (remove the entire field). In that case, the language setting (Culture) from the Windows settings will be used. For example, if the Swiss language is set in Windows, the culture of RetailVIsta POS will automatically be Swiss. One reason to use AppUiCulture is if the language within Windows is incorrect and cannot be changed for any reason.

Starting from RetailVista POS version 22.1.8065 and higher, a new field called LanguageCulture has been introduced. With this field, it is possible to specify the translation to be used for texts. The AppUiCulture is then used for the display of decimals, periods, currency symbols, etc. (Culture). Of course, it is still possible (and recommended) to omit AppUiCulture, see the above explanation. Any (existing) culture code can be used for AppUlCulture.

Below is an example of a configuration for a Swiss customer.

<AppSettings AppUiCulture="de-CH" LanguageCulture="de-DE">

By using the example below, the language setting from Windows will be read for the culture, and the 'de-DE' language files will be used for text translations.

<AppSettings LanguageCulture="de-DE">

It is not allowed to use a different code for LanguageCulture than the one for which translation files exist. Currently, these are en-US, en-GB, nl-NL, and de-DE.
