I am trying to provide a simple installer package (MSI) which I want to support with updates (patches) that supersede all previous patches. So I have a MSI V1.0.0 and 2 patches V1.0.1 and V1.0.2. The user should be able to just install the latest patch regardless which previous patches were already applied to the system. My project contains 2 features (Client and Server). The basis of the patch so is always the RTM package (HelloWorld 1.0.msi / HelloWorld 1.0.wixpdb).

The generation (build) of all patches work, so the update procedures 1.0.0 -> 1.0.1 and 1.0.0 -> 1.0.2 do, BUT when i try to update from 1.0.1 to 1.0.2 the patch fails with the following error message: "The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.". Even worse, when I run the 1.0.1 patch on a system where 1.0.2 is already installed, the patch overwrites the existing installation with an older version!? I am totally confused...

I also found several blog entries on the web about patching, but nothing that works with my supersede szenario.

我有一个类似的问题，并通过在补丁 wxs.xml 中添加适当的验证来解决它。尝试这个...

<Media Id="32000" Cabinet="HelloWorldRTM.cab">
  <PatchBaseline Id="HelloWorldRTM">
    <Validate ProductId="yes" UpgradeCode="yes" ProductVersion="Major" ProductVersionOperator="GreaterOrEqual" />
  </PatchBaseline>
</Media>

如果您不希望补丁在安装的修订号大于补丁的修订号时工作，您可能需要将 ProductVersion 更改为“Update”并将 ProductVersion 设置为“GreaterOrEqual”。

我希望这个对你有用！
