If you selected .NET version 1.1 for the .NET Framework Version property, you can specify one .NET core language that you want to distribute. This is the language that is used while the .NET 1.1 core redistributable is installed. If you selected version 2.0, the language options are all selected and disabled since they are all included with this version of the redistributable.

Click this button to launch the Redistributable Downloader Wizard, which enables you to download third-party redistributables, merge modules, and other files to assist with your project's distribution.

Refresh the list after completing the Redistributable Downloader Wizard to add languages.
