[Solved] Request: Fiddler Classic Old Version Installers and SHA256 Hashes for CNAS Testing

[linyan]

Dear Telerik Support Team,

We are an ISO/IEC 17025 (CNAS) accredited software testing laboratory in China. We need a specific old version of Fiddler Classic for controlled HTTP/HTTPS traffic capture and interface testing in our accredited test activities.

The latest public download page only provides the newest version, and the required historical build is no longer available publicly.

Could you please provide the official installer download link for Fiddler Classic version:

5.0.20262

5.0.20261

5.0.20253

And please also provide the **official SHA256 checksum** of this installer file for integrity verification.

Important notes for our quality system:

1. This installer will be used as a calibrated test tool under our CNAS quality management system (CNAS-CL01-A019:2018).

2. We need official evidence to prove the package is the original, unmodified release from Telerik.

3. We will archive your reply, download link and checksum record in our tool control file, and perform local hash validation before putting the tool into formal testing use.

4. Fiddler Classic is freeware, we confirm we will comply with its end-user license agreement.

If you cannot share the file directly, please let us know the official channel we can obtain this authentic historical release.

Thank you very much for your support.

Best regards,

linyan,Qian

Hello Linyan,

 

Thank you for contacting us and for explaining your requirements.

Telerik officially supports and distributes only the latest version of Fiddler Classic. We don't provide, archive or support older builds, including versions 5.0.20262, 5.0.20261 and 5.0.20253.

You can download the current version from the official Fiddler Classic page: https://www.telerik.com/fiddler/fiddler-classic 

For your quality records, we recommend that you:

• Download the installer directly from the official Telerik site.
• Record the version number, download date and URL.
• Compute and archive the SHA256 hash of the file you download, and check that its digital signature is valid.
• Record the version in your tool control file, and re-qualify the tool when you update it.

 

Regards,
Nick Iliev
