Hello and welcome to Advanced Installer forums,
Thank you for your interest in Advanced Installer.
Please note that you can configure a patch to be applied to more installation targets. So, when creating the
patch project, on
"Images" page, you can add more targets for your upgraded msi using the "New Target..." context menu option. When building your patch project Advanced Installer automatically makes the diff between the "Upgraded" and all its "Target" children.
You can take a look on our
Patch Authoring tutorial which will guide you step by step into the creation of a simple Windows Installer patch project. Please keep in mind that when you authoring a patch package you have a number of
restrictions.
You should also take a loon on our
patch authoring and
Building Patches and Patch Hierarchy forum threads which may be useful to you.
Please let us know if that helped otherwise give us more details about your specific scenario.
Best regards.
Dan
