    Hi all,

    I wanted to upgrade Fiddler to the latest version...

    The automatic upgrade failed so I deinstalled the current version and now I'm getting an error message: "Uninstalling the currently installed version of ... failed" .

    I cleaned up all the folders and the registry, rebooted, but it still won't install :'(

    Thanks for your help!

    Hello Stephan,

    Sorry for the late reply. Please, open Control Pannel\Programs and Features and try to uninstall the 'Fiddler Syntax-Highlighting Addons' program.

    If the solution above does not help, please, open the Registry Editor(you could type 'regedit' into the Windows' search box). Navigate to 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall' and delete the whole 'FiddlerSyntaxAddons' registry key.

    Please, let me know if you face any other issues.
