如何在卸载时应用Msi转换？(How to apply a Msi transform at uninstall?)

我正在尝试修复已经发布的基于Windows Installer的安装程序。 该修补程序用于卸载软件包时发生的错误。 为此，我想提供一个在卸载前应用的.mst转换文件。 产品安装后是否可以使用转换？ 或者可以在开始卸载之前将转换应用于已安装的.msi文件？ 我使用的命令行如下所示：

I'm trying to fix a Windows Installer based setup that is already released. The fix is for an error that occurs when uninstalling the package. For this I'd like to provide a .mst transform file that is applied before uninstalling. Is it possible to use a transform after the product was installed? Or can the transform be applied to an already installed .msi file before the uninstall is started? The command line I used was like this:

转换仅在首次安装时应用，或者在内部作为补丁的一部分应用。 要解决这样的问题，您应该考虑应用次要升级（尽管如果大小是主要问题，您应该能够将次要升级打包为补丁）。 确保传递v作为REISTALLMODE属性的一部分，以便新包替换旧包; 一般vomus对这个属性来说是一个很好的价值。

Transforms are only applied at first-install, or internally as part of a patch. To fix problems like this, you should cider applying a minor upgrade (although if size is a major concern, you should be able to package the minor upgrade as a patch). Be sure to pass v as part of the REISTALLMODE property so that the new package replaces the old one; generally vomus is a good value for that property.
