Hello,

Just wanted to start off by stating that I know there is another discussion about this called "Silent or unattended install options?" but I am unable to reply to that thread as I keep encountering an error when I try.

From this thread though, I found you can do a silent install with /S switch.

I also found from Simeon's post that you can install to a specific directory with /D=C:\Program Files\Fiddler.

My issue is that when using these switches together, I am not getting the correct result. I am deploying Fiddler (v5.0.20181.14850) via an APPLICATION. I also tried to deploy as a package but was also having issues.

FiddlerSetup.exe /S /D=C:\Program Files\Fiddler - looks like the silent install is working but then the install will fail with error 0x87D00324(-2016410844). There is a Fiddler folder within program files but the .exe was not installed.
FiddlerSetup.exe /D=C:\Program Files\Fiddler /S -Incur pop up window to walk through the instillation. The default directory on the install is correct, but it is not silent.

 

When trying to install via package, I am trying the following :

FiddlerSetup.exe /S /D=C:\Program Files\Fiddler

Issue is that it looks like it installs successfully, I can find it within C:\Program Files\Fiddler but the doesn't actually install Fiddler, seems like it just places the install within that directory.

 

I'm having an issue with an WinHTTP application I'm intercepting and modifying data for. I'm setting the WinHTTP proxy as a loopback to capture and modify the response, however the WinHTTP application checks for a loopback after the response and denies authorization if one is found.

I've tried setting the loopback, decoding the response, and right before sending my modified response, resetting the WinHTTP settings to default. The problem i'm facing is that this WinHTTP application actually polls the server twice in a row, so if I reset the proxy once, i need to set it again and then reset it again before modifying the response a 2nd time.

Is there a way I can delay the 2nd request so that I have enough time to reset and set the first one? I've tried using Thread.Sleep but that doesn't work. Thanks.

My specific role requires me to reinstall an operating system on my Window's Desktop once every other week. I am trying to write a batch/PowerShell script that does all my initial set up automatically. One thing that I am trying to automate is configuring Fiddler. Is their any way I can enable HTTPS decyption and allow all App Containers through a script?

I tried copying the files from %UserProfile%\Documents\Fiddler2  that remain after uninstalling with the option to keep your desired settings and then robocopy'ing them after I re-install Fiddler with no luck. Thank you in advance.

Q1. Fiddler Everywhere is Fiddler Orchestra?

Q2. Has the development of Fiddler Orchestra been interrupted?

Q3. Fiddler Everywhere supports mobile (Android / iOS) devices?

Hi,

I am trying to troubleshoot web services issue. When i try to call the http URL from the pc browser requests are not capturing in Fiddler. If i call the same URL from local machine browser requests are captured in Fiddler.

 

Can anyone please let me know what is the issue.

I am creating a Fiddler extension in which users will have the ability to filter the sessions in the session list. Based on the user's filter condition I want to show/hide/highlight the sessions in the Fiddler's session list. But the problem that I am facing right now is that oSession["-hide"] = true.ToString().ToLower(); does not make that session hidden. Also now I am not sure how can I highlight that session in the session list.

After set agent on mobile phone, how to capture mobile traffic via fiddllercode, like fiddler4 does.

 

Can you supply a sample code?

App looks fantastic but.... decryption coming soon?
