I have one MSI project in which i wrote an install script custom action and sequenced it to execute during Uninstallation. Inside the customaction there is an AskYesNo() function. Normal uninstallation the message is popping up and thats the desired behavior too.
My problem here is that when i try the silent uninstallation with /q or /qn or /qb still only that dialog is popping up.
Is there any way to suppress this AskYesNo dialog?
You can either check from inside of your InstallScript custom action if it is running silently, or set a condition on the said custom action so that it will not run in silent mode.
Thanks for that hint. The issue i had spotted when i am doing the major Upgrade and since the earlier product that is already installed in the machine is having this issue is there anything that i can do to supress it from my new installer?
