Get User Selection Response From PreRequisite Optional

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?

P.S. : I have to perform some other options if user selected the pre-requisite for installation, so I need to know the user's response.

I think the correct method here would be to make sure that the executable the prerequisite is running is authored to perform a correct Major Upgrade.

As long as the executable is a Major Upgrade, then it will automatically uninstall any previous versions when it runs.
