Question

Answer 1

Include waitFor(). In your case, your code will look something like below.

    Main.say("Installing...");
    Process p1 = Runtime.getRuntime().exec(dir + "setup.exe /SILENT");
    p1.waitFor()
    Main.say("Registering...");
    Process p2 = Runtime.getRuntime().exec(installDir + "program.exe /register aaaa-bbbb-cccc");
    Main.say("Updating...");
    Process p4 = Runtime.getRuntime().exec(installDir + "program.exe /update -silent");
