Unidentified Publisher on the UAC dialog when installing a patch

[DaveTu]

When installing a patch on Windows Server 2008, the UAC dialog is yellow with "Unidentifed Publisher" appearing. Both the Update.exe and the MSP are signed. The UAC dialog appears when Update button is pressed because the Update.exe is running with the asInvoker. I have confirmed that both the EXE and the embedded MSP are signed. Also I have used the same certificate to sign MSI installers that property display our company's name on the UAC dialog.

One solution is to alter the Update.exe's requestedExecutionLevel to requireAdministrator. However, I would prefer not to do this since the EXE and the UI sequence of our patch does not need the elevated privlegdes.

Any suggestions on why I am getting Unidentified Publisher?

I think that's the issue that is discussed in places such as this blog post:
