Hi,
I have the same problem.
The .net 3.5 install on a new AMD 64bit system with Windows 8 pro 64bit will not work.
Tried the several "solutions" with dism, including copying frrom DVD and re-install from HD but with no result but error 0x800f0922.
The "advise" to refresh the win8 install is no solution, I do not feel like re-installing all software that I installed from the web or from cd's.
The solution that I have for now is to run the dotnet software on a virtual XP pro in a linuxbox, isn't it a shame that microsoft, knowing this problem, is not able to bring an acceptable solution?
I know MS from back to DOS 2.2, and Windows has improved but the dotnet framework is the top in software that creates problems with all of my customers and now even with me.
Please MS look into the matter, I am willing to cooperate in searching for the cause.
Kind regards,
Jan
