我想运行一个批处理文件，我通过以下方式执行：

<CustomAction Id='InstallFilter' FileKey='install' ExeCommand='' Execute='deferred'  />

<InstallExecuteSequence>
    <Custom Action='InstallFilter' Before='InstallFinalize' />
</InstallExecuteSequence>

这将执行批处理文件，但它在 C:\Windows\System32 （或类似的东西）中运行。我希望它在找到文件的目录中运行。它不会让我用 FileKey 属性指定 Directory 属性。如何告诉安装程序用完特定目录，最好是通过目录 ID。

此外，当我尝试使用脚本卸载我的应用程序时，我收到一条错误消息，提示“Windows Installer 程序包存在问题。无法运行完成安装所需的程序。” 这是有道理的，因为当脚本运行时，文件已被删除。问题是：

  1. 如何指定我的操作应该只在安装时运行，而不是卸载？

  2. 如何卸载此当前副本？

The installer is running as the TrustedInstaller user (an admin) in elevated mode. By default, cmd.exe working folder when elevated is C:\Windows\System32. There's no way (or at least I don't know of one) to force the working folder for elevated cmd.exe to be different. (Consider the security implications of running elevated cmd -c some.cmd from random folder)

You script can take the folder it's located in and change the current folder to it like this:

setlocal
pushd %~dp0

rem ... script logic ...

popd
endlocal

You can look up the different conditions that will allow you to specify when your custom action needs to execute in @Cheeso answer to his own question how to run custom action on uninstall only. (Don't want to duplicate that information unnecessarily)

Update: If NOT INSTALLED doesn't work for you specific scenario, try NOT REMOVE.
