.NET WPF runtime error after installing with Visual Studio Installer

Question

I'm registering a global hotkey in my WPF application using exactly this approach. It works fine when debugging or running from Visual Studio, but after publishing app with Visual Studio Installer project and installing it on my PC, app throws following errors (from Event Viewer).

Things I've tried:

• running as administrator,
• disabling Windows Defender,
• running on another Windows 10 PC with no antivirus
• building in x86 configuration

Error message:

The problem was indeed a missing dll - app resources.dll. Apparently WPF app is always shipped with culture folder (en-US by default). It's copied to output directory on build (.\bin\Debug\en-US) but Visual Studio Installer doesn't pick it up and it has to be added manually.

It's done in VS Installer project's File System -> new Project Output...
