    What is your project type?
    You can achieve this using installscript using silent uninstall and then install

    Create a function for silent uninstall in installscript and call it in in custom action.
    use

    nResult = LaunchAppAndWait("Msiexec.exe", "/x {} /qn", LAAW_OPTION_WAIT);

    for silent uninstall.
