Error during uninstallation process
-
I am using QtIFW-3.1.1 binarycreator.exe to create online custom installer. When I try to uninstall , I get the following error. I am not sure from where this error pop up message is coming from. How to debug this or suppress the error message. How to ignore this error in the code? I do not want to display this pop error message to the user. No clue how to proceed further.

@user2301 Did you try to click on "Show Details" button (before error appears) to see what is going on when this error appears?
-
@jsulm Yes. I tried. But is shows nothing
-
Hi @user2301 ,
hard to say what causes this error dialog without knowing specific details?
I would first check the installscript.qs files, are you using those for control scripting?
Try to run the installer executable from command line with "--verbose" to see more traces.

@iieklund I am not sure. After upgrading to latest IFW Version: 3.1.1, built with Qt 5.9.5.. I am getting this uninstall error.
-
@Katja-Marttila, any ideas?
-
@iieklund As a workaround, I added the following line to controller script
installer.autoRejectMessageBoxes(); installer.setMessageBoxAutomaticAnswer("installationErrorWithRetry", QMessageBox.Ignore);
