如何在仅在安装或卸载时执行的WiX中执行自定义操作？ [英] How can I perform a custom action in WiX that only executes on install or uninstall?

问题描述

我有两个自定义操作，其中一个我要在安装产品时执行，另一个要在卸载产品时执行。

I have two custom actions, one of which I'd like to execute when my product is installed and the other when it is uninstalled.

我的自定义操作是当前在 InstallFinalize之后从合并模块调用，但是安装和卸载都会发生这种情况。我尝试添加未安装且未升级PRODUCTCODE条件，但这给了我一个错误：

My custom action is currently called from a merge module after the "InstallFinalize", but this happens for both install and uninstall. I've tried adding the "NOT INSTALLED AND NOT UPGRADINGPRODUCTCODE" condition, but that gave me an error:

错误2762。无法编写脚本记录。事务未开始。

Error 2762. Cannot write script record. Transaction not started.

我也尝试附加到其他操作（例如，UnpublishComponents），但找不到任何操作

I've also tried attaching to other actions (for example, UnpublishComponents), but I can't find any that are unique to install or uninstall.

如何解决此问题？
