I have the same problem as the following questions, i.e. wix created, and signed msi installer is displaying its random name while in UAC. BUT I am not using the SignTool to sign, rather the Set-AuthenticodeSignature, therefore the answers below weren’t so helpful. Now, I did read the documentation but there is nothing similar mentioned, like the /d in signtool documentation.

Is there a way to solve this, without, of course, switching to SignTool? Thank you.
