使用补丁卸载 msi 安装
我有一个产品安装，已使用一个可卸载的小更新补丁进行了修补。如果我先卸载补丁然后再安装产品，或者在补丁仍然安装的情况下选择卸载产品，有什么区别吗？产品和补丁安装是使用 WiX 工具创建的。
I have a product installation that has been patched with one small 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.

两种卸载方式的最终结果都是一样的——产品被卸载。但是，在第一种情况下，当您首先卸载补丁，然后卸载产品时，您可能会遇到其他问题。
我建议您熟悉这个文章 了解这一切是如何运作的。页面末尾提到了可卸载的补丁。之后，请务必查看 Heath 的其他有关修补的博客文章，例如：
最后，您可能想浏览该博客上的其他“安装”帖子 - 它包含许多有用的信息。
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:
Finally, you might want to browse other "installation" posts on that blog - it contains lots of useful info.
