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.

  • 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.
