I was installing Lync Server 2013 Preview in my lab and while running Step 1 from the Deployment Wizard I got the following message:
I found the Additional Software Requirements TechNet article (http://technet.microsoft.com/en-us/library/gg398686(v=ocs.15)) that lists the additional software that needs to be installed with Lync. I found Windows Identity Foundation and the link in the TechNet article directed me to download the software from here:
After downloading the software and running the installer on my Windows Server 2012 Release Candidate Front End Server, I got the following error message:
Installer encountered an error: 0x80096002
The certificate for the signer of the message is invalid or not found.
After doing a little research, I discovered that Windows Identity Foundation is built into Windows Server 2012 Release Candidate as an additional Feature that you can add via Server Manager:
After selecting Windows Identity Foundation 3.5 from the Add Roles and Features Wizard, I clicked Next and then Install. Once the installation wizard completed I ran Step 1 from the Lync Server 2013 Preview again and this time Windows Identity Foundation passed the prerequisite check:
So if you are installing Lync Server 2013 Preview on Windows Server 2012 Release Candidate, make sure that you add Windows Identity Foundation from the Add Roles and Features Wizard!
Thanks for the heads up, other articles on technet are advising to download WIM as part of the install process (which of course fails with the above error)
I just ran into the exact same issue and found the solution right here on your blog!
I have Windows Identity Foundation installed as a part of Features in Windows Server 2012.But still i am facing the same error Signature of the Message is not valid.
