I've been trying to test PowerShell Desired State configuration on a Windows Server 2012 instance on Amazon EC2. I downloaded the Windows Management Framework 4.0 from the MS download center:

Windows Management Framework 4.0


When attempting to install, I encoutered the following error:

Windows update could not be installed because of error 2148098050 "The certificate for the signer of the message is invalid or not found." (Command line: ""C:\Windows\system32\wusa.exe" "C:\Users\Administrator\Downloads\Windows6.1-KB2819745-x64-MultiPkg.msu" ")

Code signed installers normally include the certificate as part of the binary. I just right-clicked on the package and extracted the certificate manually from the MSU and installed it in the local machine certificate store to ensure the signer was trusted. When I tried to install the package again, I received a new error:

Windows update could not be installed because of error 2148073480 "Invalid algorithm specified." (Command line: ""C:\Windows\system32\wusa.exe" "C:\Users\Administrator\Downloads\Windows6.1-KB2819745-x64-MultiPkg.msu" ")

Can any one please help with resolving the above issue ?


I was downloading the wrong file. The correct file for Server 2012 was the following (from the same link posted in the question):


Installing the MSU above worked flawlessly.
