e-PocketSetup 4 has a native support for multi-language setup projects. For each project item (files, shortcuts, registry's entries, etc.) you can assign a language, and depending on selected language the project item will be installed or not. Also, all the appearance can be easily translated for all languages you want. The multi-language string table is a powerful feature, every time the setup language is changed, a variable value will be assigned with the value that corresponds to the selected language.

Also, for each setup dialog you can define variables with a language-dependent value, these variables are called Dialog Variables.

And you can translate each setup dialog's controls using the Dialog Translation Table.
