Installation 在service major升级失败时安装以前的版本

我有下面的场景

• MSI安装一个服务
• MSI对此已安装的服务进行主要升级（卸载旧版本并安装新版本）
• 在主要升级过程中，如果失败，将进行回滚，服务将完全卸载

是否可以告诉MSI，如果主要服务升级失败， 是否卸载升级并安装服务的早期版本？ 怎么做

这是我的代码：

   <CustomAction Id="SetCustomActionDataValue" Return="check"
Property="RunCmdRollback" Value="[INSTALLDIR], [UPGRADINGPRODUCTCODE],
[OLDFOUND]" />

   <CustomAction Id="RunCmdRollback" BinaryKey="OPGInstallerCA2.dll"

另一个问题。如何使回滚操作（RunCmdRollback）不是 要在升级失败时执行，是否仅在新安装失败时执行

多谢各位，

有什么原因使您无法使用WiX中的

ServiceInstall

和

ServiceControl

元素吗

看起来你让事情变得比实际需要的更复杂了
