You can try this... But fail for me :

dism /online /cleanup-image /restoreHealth
Deployment Image Servicing and Management tool
Version: 6.3.9600.17031

Image Version: 6.3.9600.17031

The restore operation completed successfully. The component store corruption was repaired.
The operation completed successfully.

This operation takes a lot of time ~40min

After you install security update 2966827 or 2966828 (described in Microsoft Security Bulletin MS14-046) for the Microsoft .NET Framework 3.5 and then try to enable the optional Microsoft .NET Framework 3.5 feature in Windows Features for the first time, the feature may not be enabled.

--> The problem seems resolved by this update : https://support.microsoft.com/en-us/kb/3002547
But in my case, I've always got the problem....

I'll try to get framework 3.5 from another source (from cd) and I'll post my test ;)
