Uninstalling msi installation with patches

I have a product installation that has been patched with one smal开发者_C百科l update patch which is uninstallable. Is there any difference if I first uninstall the patch and then product installation or if I select the uninstall of the product while the patch is still installed? Product and patch installations are created using WiX tools.

The final result of both ways to uninstall is the same - the product is uninstalled. However, you might potentially face with other problems in the first case, when you first uninstall a patch, then the product.

I would recommend you to get acquainted with this article to understand how it all works. The end of the page mentions uninstallable patches. Afterwards, be sure to check other Heath's blog posts about patching, like:
