[wix-users] Unknown publisher UAC in Windows 7 only

Wed Sep 6 10:10:36 PDT 2017

Win 7 machine is connected to the internet and is at least SP1. It is a test machine and has not been used in a few months so I am updating it now.

On the Windows 7 machine the Bundle shows dual signed certs in the 'Digital signatures' tab: SHA256 and SHA1

I use this powershell (run from TeamCity) script to sign everything. The MSI is signed in a different step and I checked and it's 'Digital signatures' tab shows SHA256

rem # --- extract the burn engine

Is the Win 7 machine connected to the internet?  Has it had all the windows updates applied?

When you look at the bundle on the Win7 machine, what does the certificate look like?

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?

Thanks.
