Fiddler2 direct download

Posted by jpluimers on 2017/06/06

For automated installs that cannot have UI interaction:

The install is “per user” as it is a user-local application; it installs in %LocalAppData%\Programs\Fiddler\Fiddler.exe.


Note that Fiddler acts as a HTTP proxy. When Fiddler starts, it hooks itself into the default WinINET proxy (which is used by any tool using the WinINET API, including Edge, Internet Explorer, Chrome, but not FireFox).

If you kill your Windows machine before stopping Fiddler, it cannot restore the WinINET proxy, so you have to do that by hand (otherwise you cannot browse web pages any more).

Manual restore:

  1. Run "C:\Windows\System32\rundll32.exe" shell32.dll,Control_RunDLL inetcpl.cpl,,4
  2. Press “LAN settings” (Dutch: “LAN-Instellingen”)
  3. Uncheck the proxy server checkbox “Use a proxy server for your LAN” (Dutch “Een proxy-server voor uw LAN gebruiken”)
  4. Confirm
  5. Close the control panel wizard
