Within PreRequisite Editor, I have marked the option for user to optionally skip the installation in a prerequisite. Now, when the installation runs, there's a dialog box that says "[ProductName] optionally uses PreRequisite. Would you like to install it now?". I want to uninstall any other version of that prerequisite if user has selected Yes,else I do not want to uninstall the other version. How do I know if the user has selected Yes/No in the pre-requisite option dialog box?
I checked the logs but didn't find any properties that get modified during the InstallPrerequisites step during installation.
P.S. : I have to perform some other options if user selected the pre-requisite for installation
