    For a few months now on my Windows 10 machine I can't start Fiddler successfully.

    Here's what I get in the Event logs:

    Hi,

    From the log I can see that you are using very old version of Fiddler. Please, update to the latest version and try running it again.

    I downloaded the installer on Jan 30th and it's anyone's guess how this could be an old version. Removed and reinstalled it, still no luck. Where does it show the old version? Which is the current version that should work?

    Here?

    Hello,

    Would it be possible to share the contents of "C:\Program Files (x86)\Fiddler2" and "%LOCALAPPDATA%\Programs\Fiddler"?

    Hello,

    Attaching a screenshots or a text files with the contents of the folders would suffice.

    Hello,

    Something seems to went wrong during the installation process. The steps to fix it are:

    1. Uninstall Fiddler though "Apps and Features".
    2. Go to "C:\Program Files (x86)" and delete the "Fiddler2" folder.
    3. Go to "%LOCALAPPDATA%\Programs" and delete the "Fiddler" folder.
    4. Install the newest version of Fiddler.

    This should fix the problem.

    Hi,

    The newest version of Fiddler installs into %LOCALAPPDATA%\Programs\Fiddler folder by default and not into C:\Program Files (x86)\Fiddler2 anymore. It seems that for some reason the old version of Fiddler is being run:

    Same with a fresh installer dated TODAY

    Faulting application name: Fiddler.exe, version: 4.6.3.50306, time stamp: 0x584b0128

    Could you, please, go to %LOCALAPPDATA%\Programs\Fiddler and run the Fiddler.exe
