************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>


    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.

推荐答案

您必须检查的路径你exe文件，如果斌存在

you have to check the path of your exe if bin exist

string path;
if(Application.StartupPath.LastIndexOf("bin") >0)
   string path = Application.StartupPath.Substring(0, Application.StartupPath.LastIndexOf("bin"));
else
{
  string path = string.Empty
  MessageBox("Check your path : " +   Application.StartupPath);
}
