You're running Windows 8, and for some reason or another need to install the .NET Framework 3.5. Open up the Windows Features dialog, and its totally blank, without any add/remove options. What the heck?
Each of these command can take upwards of an hour to run. BE PATIENT, some of the dialogs sit there a while and seem to be stuck, but they're not. Open an elevated command prompt and run the two following commands
sfc /scannow dism /Online /Cleanup-Image /RestoreHealth
Although it didn't match my situation directly, I binged around and found this post ( http://social.technet.microsoft.com/Forums/windows/en-US/732ad60c-ecc6-4801-ac16-da474dace19f/problem-with-windows-features-on-or-off ) which offered some potential solutions to fix Windows Features issues. I ran the commands as listed in the FIX section above. . After the command ran and I rebooted the machine, I could use Windows Features to install the .NET Framework 3.5 on my Windows 8 box. I didn't think the command would take over an hour to run, and well, might have killed them once or twice when I thought they were stuck, so watch out.
Posted here for the SEO gods in the hope it doesn't cost someone else the 4 hours of research and fix that it took to resolve the issue.
