Hello and welcome to our forums,
The "Install" and "Uninstall" processes are as straight forward as they could be. Simply add your resources to the Advanced Installer project, build the project and run the setup. To uninstall it, just use the "Control Panel".
You can check our
"Creating a Professional package" article for this, which I think you may find useful.
In what regards the
"Upgrade", if you want to perform a major upgrade, all you need to do is to change the
"Version" from the
"Product Details" page and then generate a new
"Product Code".
In what regards creating of a
Patch, please have a look on our
"Creating Patches" article.
To see the differences between a Patch and a Major Upgrade, please have a look over our
"Updates Deployment: Major Upgrade vs Patch" article.
Hope this helps.
Best regards,
Catalin
