Installing Windows Identity Foundation on Windows 8 - The Certificate for the signer of the message is invalid or not found.

 

Just a very quick note here, in case you’re struggling to get Windows Identity Foundation installed on your Win8 development machine.

Have you been setting up another development machine for Azure development on Windows 8, and have run into a problem installing the Windows Identity Framework?  Yeah, me too.  The error message is “Windows Update Standalone Installer.  Installer encountered an error 0x80096002. The certificate for the signer of the message is invalid or not found.”

The short answer is that WIF is managed on Windows 8 using the “Turn Windows Features On and Off”.  You can get that by:

1. Punch that Windows key!

2. Type “Windows Features” and make sure you’ve chosen to search “Settings” from the search pane.

3. Click on “Turn Windows features on or off”

4. Check the box next to “Windows Identity Framework 3.5” (and yes, this supports .NET 3.5 and 4.0 applications).

5. Press “OK” and let setup do it’s thing.

You’re welcome!
