I'm running the 180-day trial of Windows Server 2012 Essentials. The client computer has Windows 8 Pro (64-bit) installed.

A few days ago, a security update for the Microsoft .NET Framework (KB2840632) was installed automatically via Windows Update on the client (twice; the first installation attempt failed, as seen in the Windows Update history), and since then the client app for the Windows Server 2012 Essentials Dashboard won't start anymore. After launching the app, there is some activity, but the Dashboard doesn't launch. In the Event Viewer on the client, these errors appear (in Dutch):

.NET Runtime

Toepassing: DashboardClient.exe

Framework-versie: v4.0.30319

Beschrijving: het proces is beëindigd als gevolg van een onverwerkte uitzondering.

Remove the .NET update until an adequate fix has been made?

When I try to uninstall the update, I get a non-specific error. I believe something went awry during the installation of the update, because I don't know someone else who has the problem also. sfc /scannow didn't help either. –  eprillios Aug 25 '13 at 10:56
    
Sorry no idea :( .. I tried doing some research and I'll I found was run the visual studio debugger type answers :( –  Aceth Aug 25 '13 at 16:00

As it is only an evaluation, why not take a backup of the AD if needed and just rebuild? avoid that patch in future
