Error when trying to add Windows Communication Foundation HTTP Activation in Windows Vista

I'm trying to add Windows Communication Foundation HTTP Activation (and Non-HTTP Activation) to my Windows Vista Ultimate x64, but it doesn't work.

I go to the Control Panel
Select the Turn Windows features on and off
Expand the Microsoft .NET Framework 3.0 node
Select Windows Communication Foundation HTTP Activation
Click OK.

When I do that, I get a progress bar that doesn't really do anything for 5 minutes. Then it slowly progresses to the right and sits there for another 5-10 minutes before giving up with this error:

An error has occurred. Not all of the features were successfully changed.

The feature is not installed, but there's nothing in the Windows Event Log.

I really need this feature working, so any help would be appreciated.

Have you installed IIS recently? Rebooted since?

I've had a seemingly working IIS install block several other Vista/Server2008 component installs. I ended up uninstalling IIS and then doing a clean install of IIS + the other components in one go.

No way sure that's your issue, but can't hurt trying.

Uninstalled IIS, rebooted, attempted install again. Nothing seems to be working. FWIW, the WCF features are not part of IIS (not in the features tree at least)... – Mark Seemann – 2010-01-28T21:18:40.597

Maybe it would help to follow the steps from Windows Server 2008 as development machine - step by step

Thanks for the suggestion, but .NET seems to be working fine. I tried out some of the troubleshooting steps and so, but to no avail. – Mark Seemann – 2010-01-29T08:23:22.843

All other google results are in the line of: Windows Update then .NET Framework 3.5 SP1 (full package, around 231 MB), and then WCF activation should work – alexandrul – 2010-01-29T08:52:34.193
