The Application languages dialog box can be started from File > Options > Startup, by clicking Add Language. This dialog box serves as a tool to add application languages to the Application Language list. The list is populated with the application languages available at the moment, consisting of two columns.
Installed, if the language is already installed.
Available, if the language is not yet installed on this computer, but available for download and installation.
Downloading, if the user has just initiated the installation and download is in progress.
Installing, if the user has just initiated the installation, and download is finished, but installation is still in progress.
Failed to download, if the download was not successful.
Failed to install, if the installation was not successful.
Select the desired language, then click Add to start the download and the installation. (Windows requires the user to have administrative rights on the computer and asks for confirmation.)
Click Close to return to the Options page, where you may select the new language in the Application language list.
