Trados Studio 2024 breaks access to IATE in all browsers (Windows 11)

Hello,

After installing Trados Studio 2024 on a new Windows 11 computer, we are no longer able to access IATE (https://iate.europa.eu) on this machine — in any browser (Chrome, Edge, Firefox).

Important observations:

  • IATE works without issues on another computer on the same network
  • The problem occurs only on the computer where Trados Studio 2024 was installed
  • The issue affects all browsers, including fresh profiles and private windows
  • No IATE plugin has been installed in Trados
  • During Trados startup, we receive a popup stating that IATE could not be loaded
  • The IATE web interface loads but remains dimmed and non-interactive, consistent with a blocked WebView / authentication layer

Troubleshooting already performed:

  • Tested Chrome, Edge, and Firefox (including new profiles and private windows)
  • Disabled antivirus and browser extensions
  • Verified Windows proxy settings (no proxy configured)
  • Verified system date/time and TLS settings
  • Confirmed that the issue persists even when Trados is not running
  • Confirmed that the issue started immediately after installing Trados Studio 2024

Based on this, we conclude that the issue is not browser-related, not network-related, and not account-related, but rather caused by a system-level component installed or modified by Trados Studio 2024 (most likely WebView2 / WinINET / TLS configuration).

We therefore request:

  • Confirmation that this is a known issue with Trados Studio 2024
  • Guidance on how to repair or reset the affected Trados-installed components
  • Instructions for restoring full IATE web access without uninstalling the operating system

At present, Trados Studio 2024 effectively breaks access to IATE on this system, which is a critical resource in our translation workflow.

We look forward to your technical guidance.

  • Hi 

    A reset might help you with this.  To do this just close Trados Studio and then delete these folders:

    %appdata%\Trados\Trados Studio\Studio18\

    %appdata%\Trados\Trados Studio\18\

    You will lose your plugins, and also your settings, but your projects and other resources will remain untouched. Putting the plugins back is trivial via the integrated appstore.

    If you can't find these folders then you need to unhide your hidden files/folders:

    Then restart Trados Studio and see if that helped.

    Kind regards,

  • Hello,

    Following your instructions, we have now completed the reset and verified the results.

    Actions taken:

    • Trados Studio was fully closed
    • The following folders were reset (renamed to preserve backups):
      • %appdata%\Trados\Trados Studio\Studio18\
      • %appdata%\Trados\Trados Studio\18\
    • The system was restarted
    • Trados Studio 2024 recreated both the Studio18 and 18 folders correctly on startup

    Result:

    Unfortunately, the issue persists unchanged.

    • IATE (https://iate.europa.eu) remains inaccessible in all browsers (Chrome, Edge, Firefox)
    • The page does not load
    • The behaviour is identical before and after the reset
    • IATE works normally on another computer on the same network

    Given that:

    • the Trados Studio 18 user environment is recreated correctly,
    • resetting the local configuration has no effect,
    • and the issue began immediately after installing Trados Studio 2024,

    this points to a system-level component affected by the Trados Studio 2024 installation (e.g. WebView2 runtime, WinINET, TLS or certificate handling), rather than a user-profile or plugin issue.

    Please advise on the next diagnostic or repair steps, or on how this can be escalated.
