Qt Installer Framework: How to sign the maintenancetool.exe

Question

I have build an installer for my application with the QtIFW2.0.1 on Windows. As we offer the installer for download, I have signed the installer executable with a valid certificate. So our verified name shows up while the installation process ask for the needed access rights. Nevertheless there is an unpleasant messagebox if the user uninstalls, updates or changes our application via the maintenancetool.exe. How is it possible to extract the maintenancetool.exe, sign it and put it back in the installer executable?

Answer 1

Maintenancetool signing in Windows (QTIFW-667) is possible since Qt Installer Framework version 3.1.0 which was released April 11th 2019.
