I need to prepare an installer package through Innosetup that installs the .Net 3.5 if not available in the system: this setup should run on any windows system, and should be run offline: is there a simple way to do that? Actually I made a package that self contains the framework installer, it works well in systems from XP to win7, but not on win 8.1 and windows server 2012... On those systems I've found that I could use the Dism tool, but that way I should provide the WinSxs sources too: I guess this could be the right way, but the question is what are the sources needed to install the framework correctly?
Any help appreciated, thanks
