Thank you for your question and for reaching out with your question today.
If you're struggling to understand the link you provided, then I highly recommend The Definitive Guide to Windows Installer: https://rads.stackoverflow.com/amzn/click/com/1590592972 It may also be worth downloading the Windows Installer 4.5
If you don't want to learn the Windows Installer fundamentals, then you'll need a wizard to hide all the intricate details and hold your hand through the process.
There are loads of options, some more costly than others: MSI Factory InstallShield Advanced Installer However, I would recommend that you read the aforementioned book and learn the fundamentals of what's going on in order to maximise your chances of creating an effective MSI.
