Enabling capture causes exception

I get the following exception saying to quit or continue the application, if I continue capture does not begin.

Here's the content of the error:

See the end of this message for details on invoking

************** 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.

Hello Patrick,

Do you mean that the check box for starting as system proxy is unchecked, as I just checked the code and it seems we are not disabling it (it should become grayed out in this case) anywhere?

Otherwise, we investigated the call stack again, and the method that's failing is InternetSetOption in wininet.dll. What's happening behind the scenes:

- on startup, Fiddler is getting the network connections for the OS, and replaces their proxy settings with the ones pointing to the port it's listening onto (127.0.0.1:8888 by default). It seems the "replace step" is the one that fails

- on exit, Fiddler is restoring the previous settings proxy settings.

That said, probably there are some obscure network connections (or proxy settings for these connections), which are breaking the Win32 call we are making. Could you check whether you have some "strange" or non-trivial network connections, or whether you use some proxy by default (e.g. some corporate proxy)? 

Also, something that could probably help is to enable DebugSpew mode (by adding the DebugSpew regkey), in which Fiddler logs messages to the debug output. These messages can be monitored using DebugView for example.

I also did a quick research, but it seems the error is not so common case - anyway I am posting it here in case you recognize some of the scenario mentioned, e.g. the Error Message: Proxy Reports: 87 The parameter Is Incorrect one.

Boby

The check box for start as system proxy is disabled. I reverted to the Fiddler on the website since the code you provided via zip would not start at all. So now, even with SAZ, I can not manually start tracing as it leads back to the the debug screen I post in the beginning of this bug report.

Please let me know what you'd like me to try next.

Thank you for your continued patience.

Hello Patrick,

I misunderstood you that double clicking on a SAZ file permanently fixed the problem.

When double clicking a SAZ file, Fiddler starts with capturing disabled. This got me thinking that maybe the code is running in a concurrency issue during the normal startup, which is done with capturing enabled. Could you try to disable the capturing on startup, to check whether this will fix the problem as well? There is setting in Tools -> Options -> Connections -> Act as a system proxy on startup. When disabled, you would need to manually start capturing after app start (convenient way is to use the F12 keyboard shortcut). This could as well be a more pleasant workaround that always starting using a SAZ file.

Okay, thank you for the update. At least for now I have a work around of starting up via an archive file.

Hello Patrick,

Thanks for the information, I will decline the bug report for now, though with unknown reason. If you find additional information, we can go back to investigation phase.

Boby,

An update, I opened Fiddler via double-clicking an archive and fiddler opens/loads archive. Also, capture works.

Boby, I've replaced those files and now Fiddler doesn't get past start screen. (see attached)

Hello Patrick,

Thank you for the additional information.

Our current thinking is that we are trying to push the adoption of the newest versions, so official archive of previous versions is not provided. Instead, could we try to debug this a little further - if possible, could you try copying the attached files to the following places:

- Telerik.NetworkConnections.dll and Telerik.NetworkConnections.pdb to the Fiddler install directory (by default C:\Users\<username>\AppData\Local\Programs\Fiddler). Overwrite the files with the same name.

- Telerik.NetworkConnections.Windows.dll and Telerik.NetworkConnections.Windows.pdb to the Plugins directory (by default C:\Users\<username>\AppData\Local\Programs\Fiddler\Plugins\NetworkConnections)

This will ensure that PDBs are locally present, and will give us better call stack with source code line numbers (including for the top of the stack, where currently they are missing) at the moment of the exception.

Boby

Do you by any chance use 32-bit version of Windows 10? No, its 64-bit

Was this working in previous Fiddler versions (especially versions prior 5.0.20192.2 5091, for which we have reports as well)? It was working in prior version, but not sure what that was. Is there an archive area where I can download an older version to see if problem goes away?

Hi Patrick,

We've had similar error reports in the past (see here) but the reason is still unknown to us as we cannot reproduce the issue locally. Do you by any chance use 32-bit version of Windows 10? Was this working in previous Fiddler versions (especially versions prior 5.0.20192.25091, for which we have reports as well)?
