我有一个自定义操作，返回ActionResult.UserExit，据我所知，应该停止安装继续进行。然而，情况似乎并非如此。安装继续，就像自定义操作成功一样。

自定义操作CheckMILInstallation定义为：

<CustomAction Id="CheckMILInstallation" BinaryKey="CustomActions" DllEntry="CheckMILInstallation"></CustomAction>

并从对话框按钮触发：

<Publish Dialog="DASetupTypeDlg"       Control="Back" Event="NewDialog" Value="DALicenseDlg">1</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Event="DoAction"  Value="CheckMILInstallation" order="1">1</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="NextDialog"                 Value="VerifyReadyDlg" Order="2">1</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="VerifyReadyDlg_Back"        Value="DASetupTypeDlg" Order="2">1</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="NextDialog"                 Value="DAInstallCSWDlg" Order="3">INSTALLIDE="1" AND VS2010_VCSHARP_FOLDER</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="DAInstallCSWDlg_Back"       Value="DASetupTypeDlg"  Order="3">INSTALLIDE="1" AND VS2010_VCSHARP_FOLDER</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="NextDialog"                 Value="DAStartWebsiteDlg" Order="4">INSTALLRT="1" AND CONFLICTING_WEBSITE</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="DAStartWebsiteDlg_Back"     Value="DASetupTypeDlg"    Order="4">INSTALLRT="1" AND CONFLICTING_WEBSITE</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="NextDialog"                 Value="DAMultiInstallDirDlg" Order="5">InstallPathEditable OR ExamplesPathEditable</Publish>
<Publish Dialog="DASetupTypeDlg"       Control="Next" Property="DAMultiInstallDirDlg_Back"  Value="DASetupTypeDlg"       Order="5">InstallPathEditable OR ExamplesPathEditable</Publish>      
<Publish Dialog="DASetupTypeDlg"       Control="Next" Event="NewDialog" Value="[NextDialog]" Order="6">1</Publish>

MSI日志确实指示了正确的返回值，但随后继续创建下一个对话框，就像它成功了一样：

Action 11:05:56: CheckMILInstallation.

我在这里缺少什么？

我不确定您的ActionResult.UserExit的定义位置，但文档似乎表明该值应为1602，而不是2为用户出口。值2似乎保留用于脚本自定义操作的结果。

脚本CA返回值：

返回ActionResult.UserExit似乎没有任何效果
