使用 WiX 创建第二个服务包
如何使用 WiX 为您的应用程序创建第二个服务包？ 我已经发布了 SP1，并且该安装程序运行良好。 但我在使用 SP2 时遇到了一些困难。 我当前的 WiX 设置已从原始 (RTM) 版本正确升级。 但是，如果我尝试从 SP1 升级，文件根本不会更新，尽管它在“添加/删除程序”中显示为 SP2。 我需要做什么才能使升级成功？ 我已将另一个
我应该对 SP2 进行哪些更改？
How do you use WiX to create a second service pack for your app? I’ve released SP1, and that installer works fine. But I’m having some difficulty with SP2. My current WiX setup upgrades from the original (RTM) version correctly. But if I try to upgrade from SP1, the files simply don’t update, although it shows as SP2 in Add/Remove Programs. What do I need to do to make the upgrade work? I’ve added another <TargetImage> to my <UpgradeImage> Other than that, I’m largely following the example from http://wix.sourceforge.net/manual-wix2/patch_building.htm changing to the version number from 1 to 2.
What changes should I be making for SP2?

我发现了我的错误。 我更改了
PatchFamily的值（在PatchFamily更改为其旧值，并且我的补丁构建成功。I found my error. I had changed the value of
PatchFamily(under<PatchSequence>). This caused it to think of SP1 and SP2 as two different "families", so SP2 did not override SP1, even though it had a higher number. I changedPatchFamilyto its old value and my patch built successfully.
