Post Install Option to Re-Open a Conflicting Process if it was Running

Today you can create a post-install script that will re-open an executable once the install has finished. However, I only want to re-open the executable if it was running at the time of install and had to be closed because it was a conflicting process. I would like the option to either have certain scripts only run when a conflicting process was open before installation OR a checkbox that says to re-open any conflicting processes that were found before installation.
