How to enable JIT debugging for a certain app?

Im using an internet tracker app called Net Uptime Monitor, Recently it came up with a panel that says,

"Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click QUIT, the application will close immediately

Configuration system failed to initialize"

Heres the full line of code

See the end of this message for details on invoking

just-in-time (JIT) debugging instead of this dialog box.

************** 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>

```yaml
<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.

    If you’re talking about the source code/symbol files are you talking about the “exe” file?

    @Brendan Price, source code is this application’s code, written by developers. It’s different from a .exe file.

    A symbol file ends with .pdb is a program database file. It includes debugging information, maps identifiers and statements in source code to corresponding identifiers and instructions in compiled apps. The mapping file links the debugger to the source code, which enables debugging. It’s needed when you are going to debug the corresponding application.

    I’ll try to see if I could contact the creator perhaps or see if they possibly already have a fix.

    The application you want to debug is an existing application, without these files(source code files, symbol files), only the exe file and some other files. Yes, you probably need to contact the creator to debug this application as they have the source code and symbol files for debugging. They can better understand the exception and find the cause in their application.

    Feel free to let us know the results:)

    Besides, if you try to use the "Attach to Process" feature in Visual Studio to debug that application, will it work? Kindly check this document: Attach to running processes with the Visual Studio debugger for more details.

    Best Regards,

    Tianyu

    Needed to just delete the files and redownload the app.
