使用msi文件安装程序时不会捕获异常

I made a WPF program that works in the VIsual studio when run. I made an installer for my program with Visual Installer Projects 2017. At one part the program crashes and I get the following dialog:

我制作了一个WPF程序，可以在运行时在VIsual工作室中运行。我使用Visual Installer Projects 2017为我的程序安装了一个安装程序。在一个部分程序崩溃，我得到以下对话框：

An unhandled Microsoft.NET Framework exception occured in Program1.exe [10204].

Program1.exe [10204]中出现未处理的Microsoft.NET Framework异常。

My catch block looks like this

我的catch块看起来像这样

Dispatcher.Invoke(new Action(() =>
            {
                EnableContent();
            }));
        }
        catch (AggregateException e)
        {
            MessageBox.Show(e.ToString());
            Dispatcher.Invoke(new Action(() =>
            {
                UpdateLoadMsg("No internet connection.", MsgType.FAIL);
            }));
        }
        catch (Exception e)
        {
            MessageBox.Show(e.ToString());
            Dispatcher.Invoke(new Action(() =>
            {
                UpdateLoadMsg("Something went wrong.", MsgType.FAIL);
            }));
        }

Messagebox is never showed! apparently the exception isn't being catched. How to debug this?

Messagebox永远不会显示！显然这个例外没有被抓住。如何调试？

I found the causing exception by looking at the system logs http://www.dummies.com/computers/operating-systems/windows-10/how-to-use-event-viewer-in-windows-10/ .

我通过查看系统日志http://www.dummies.com/computers/operating-systems/windows-10/how-to-use-event-viewer-in-windows-10/找到了导致异常的原因。

Non-relevant

The exception that was being thrown was a FileNotFoundException. Setting buildaction = embedded resource wasn't enough, I had to add the file as additional installation file.

抛出的异常是FileNotFoundException。设置buildaction =嵌入式资源是不够的，我不得不将该文件添加为附加安装文件。
