Signing does not work after installing KB5074109

[jusvu]

Hi! I have been using Advanced Installer for years and it has been working great. Now, when I received the Windows Update KB5074109, signtool stopped working. If I uninstall the update, it works OK, but since my PC is company IT controlled it keeps pushing the same update again and again. Have you seen this kind of problem? Any advice what I might try?

Here's the error I see:

Code: Select all

...forgot to say that if I call Signtool from command prompt, it works OK.

Here's the command I use (which works OK):

Code: Select all

"C:\Program Files (x86)\Caphyon\Advanced Installer 23.5.1\third-party\winsdk\x64\signtool.exe" sign /debug /fd SHA256 /sha1 <my_cert_thumbprint_here> MyApp.exe

More information on this: I tried to run the sign command in command prompt and it works:

Code: Select all

"C:\Program Files (x86)\Caphyon\Advanced Installer 23.5.1\bin\x86\AdvancedInstaller.com" /build "D:\GitLab\MyApp\MyAppSetup\MyAppSetup.aip" -buildslist DefaultBuild -drop_content

I suspect the problem is with Advanced Installer Visual Studio extension. I tried to uninstall/install the VS extension, but it didn't help.

Could you check what those error codes mean? I couldn't find any information about them.

I updated to Visual Studio 2026 -> installed the new Advanced Installer VS extension 2026 and signing works now OK !
