I have compiled an installer for my application with QtIFW2.0.1 on Windows. Since we offer the installer for download, I signed the installer executable with a valid certificate. Thus, our verified name appears while the required access rights are requested during the installation process. However, an unpleasant message appears if the user removes, updates or modifies our application using maintenancetool.exe. How can I extract the maintenancetool.exe file, sign it and put it back into the installer executable?
