With the upcoming Fiddler Everywhere 5.0 release, the application will no longer be supported on Windows 7, Windows 8 and Windows 8.1. Upgrade to Windows 10 or higher to ensure uninterrupted flow.

What to Expect?

With the upcoming Progress Telerik Fiddler Everywhere 5.0 release, the application will no longer be supported on the following Windows versions:

  • Windows 7
  • Windows 8
  • Windows 8.1

The change is scheduled for late October 2023. After that, you will no longer be able to start the Fiddler Everywhere application if you are operating on one of those Windows versions.

Why This Change?

We are introducing this change because we want to use the latest frameworks and technology within Fiddler Everywhere, which require a higher Windows version to function. The up-to-date technologies will ensure a higher security of the application, which means higher security for our Fiddler users.

The usage of latest technologies will also give us access to new functionalities, and this will result in faster release iterations on our side, as well as easier development of features in the app.

In addition, we are following the same practices as Microsoft which ended the extended security updates for these versions in the beginning of 2023. These versions are officially not supported by Microsoft, and it only made sense for us to follow suit and aim for technology and security excellence.  

What Can You Do?

To be able to start Fiddler Everywhere and continue using the application after this date, you need to upgrade your version to Windows 10 or higher. Keep in mind that the application will not start on a device with Windows 7, 8 or 8.1.

The Fiddler Everywhere version updates are automatic and older version of the application will not be supported, and you will not be able install a previous version of the app on your device. Get the latest Fiddler Everywhere from our download page.
