WIX - Run custom action on installation cancellation
问题 I'm wirintg an installer using WIX and I need to execute a custom action when a user press the "cancel" button. I've created a custom action but I don't seem to find where to use that action. Any ideas how can I do that? 回答1: Try something like: <Custom Action="MyAction" OnExit="cancel">1</Custom> 回答2: OnExit="cancel" may fail if standard WIX UI is used (WIX assigns another action to "cancel" event). Action execution could be assigned to finish button in this case <Publish Dialog="UserExit"
