Installing a GV STRATUS language pack

Download one or more GV STRATUS language packs. Each downloaded language pack is a zip file.
Unzip a downloaded file. The unzipped file is a directory, named for the language.
Put the directory in your GV STRATUS install location. By default, the GV STRATUS install location is C:\Program Files\Grass Valley\STRATUS.

You can now select the language in GV STRATUS User Preferences.
