This property specifies the location from which your installation downloads the .NET Framework runtime and the J# redistributable, if included. It is not necessary to specify the file name in the URL.

1. This property is required only if the .NET Framework Location or J# Redistributable Location property (if included) for the current release is set to Download from the Web.
2. The installation downloads and runs the InstallShield file Dotnetfx.exe, which in turn downloads Dotnetredist.exe from the Microsoft Web site. This behavior is hardcoded in Dotnetfx.exe, which can be hosted anywhere.
