I use Trados 2017 and I can't load "sdl.desktopeditor.control.dll"

I am using Trados 2017 as specified by the client, but when I attempt to open a project, I receive the error: “Unexpected exception when getting view part instance of view part Translation Results,” along with “Failed to load file or component ‘sdl.desktopeditor.control.dll’ or one of its dependencies. Not a valid Win32 application.” (Exception occurred at HRESULT: 0800700C1).

My current operating system is Windows 10. I have tried all the fixes suggested on forums, including reinstalling Microsoft Visual C++ Redistributable, but the issue persists. I would appreciate any assistance in resolving this. Thank you!

    The error you are seeing points to a problem with the local Trados Studio installation rather than the project itself.  In practice, this is most often caused by a corrupted installation, an incompatible plugin, or interference from other Trados Studio versions installed on the same machine (because 2017 is not as well separated as more recent versions).

    Before continuing, it is important to clarify the support status.

    End-of-life status

    Trados Studio 2017 and MultiTerm Desktop 2017 are end of life.
    Engineering and technical support for these versions ended on 31 January 2021.  Since that date, standard maintenance services, including technical support, updates, and new patches, are no longer available.

    This means there are no fixes for issues introduced by newer Windows 10 updates, and any resolution is limited to local workarounds.  There is no guarantee that Studio 2017 will continue to function reliably in a modern Windows environment.

    Recommended troubleshooting steps

    You can try the following steps, in order.  These resolve many cases, but success cannot be guaranteed due to the age of the product.

    1. Start Studio without plugins

      • Close Trados Studio.

      • Rename the following folders:

        %APPDATA%\SDL\SDL Trados Studio\14\Plugins
        %LOCALAPPDATA%\SDL\SDL Trados Studio\14\Plugins
        %PROGRAMDATA%\SDL\SDL Trados Studio\14\Plugins
        
      • Restart Studio and try opening the project.

      • If this works, the issue is caused by a plugin.  Reintroduce plugins one at a time (if you really need them - maybe one or more might still work).

    2. Repair the Studio installation

      • Go to Apps & Features.

      • Select SDL Trados Studio 2017ModifyRepair.

      • Reboot and test again.

    3. Clean reinstall

      • Uninstall Trados Studio 2017.

      • Manually remove any remaining folders:

        C:\Program Files (x86)\SDL\SDL Trados Studio\Studio14
        %APPDATA%\SDL\SDL Trados Studio\14
        %LOCALAPPDATA%\SDL\SDL Trados Studio\14
        %PROGRAMDATA%\SDL\SDL Trados Studio\14
        
      • Reinstall Studio 2017 and test before installing any plugins.

    4. Check for other Studio versions

      • If other versions of Trados Studio (2019, 2021, 2022, etc.) are installed or were previously installed, temporarily uninstall them and test Studio 2017 in isolation.

    5. Antivirus exclusions

      • Ensure the Studio installation folder is excluded from real-time antivirus scanning, as older Studio versions are more prone to DLL interference.

    Final note

    Even if one of the steps above resolves the issue, stability cannot be guaranteed long-term.  Studio 2017 is simply too old to be reliable on current Windows systems, and any future Windows update may reintroduce the problem.

    Where possible, the only supported and sustainable solution is to upgrade to a currently supported version of Trados Studio, even if the client requires delivery in a Studio 2017-compatible format.  Perhaps there is another way to provide your client with an appropriate file to update their system.  What is the final delivery?
