这是适当的Wix文件中的位：

<Binary Id="INSTALLERHELPER" SourceFile=".\Lib\InstallerHelper.dll" />
<CustomAction Id="HelperAction" BinaryKey="INSTALLERHELPER" DllEntry="CustomAction1" Execute="immediate" />

这是我的自定义操作的完整类文件：

using Microsoft.Deployment.WindowsInstaller;

namespace InstallerHelper
{
  public class CustomActions
  {
    [CustomAction]
    public static ActionResult CustomAction1(Session session)
    {
      session.Log("Begin CustomAction1");

      return ActionResult.Success;
    }
  }
}

该操作由UI中的按钮按下(现在)：

<Control Id="Next" Type="PushButton" X="248" Y="243" Width="56" Height="17" Default="yes" Text="!(loc.WixUINext)" >
      <Publish Event="DoAction" Value="HelperAction">1</Publish>
  </Control>

当我运行MSI时,我在日志中收到此错误：

它给我的两个错误代码或消息都不足以告诉我什么是错的.或许我只是不明白他们说的是错的.

起初我以为可能是因为我使用的是Wix 3.5,所以为了确保我尝试使用Wix 3.0,但我得到了同样的错误.

关于我做错的任何想法？
