Hi all.

I am having an issue with the elevated prompt showing 'Unknown' publisher from my burn engine.

Everything works fine in Windows Server 2008, 2012, 2016 and Windows 10. It only fails on Windows 7 SP1.

Both the burn engine and the bundle are signed with SHA256 and SHA1. The MSI is signed with SHA256 and looking at the properties of the installer you can see the digital signatures.

I have been trying to fix this for 2 days now. Why would it fail on Windows 7?

Anybody seen this before?
