After installing Trados Studio 2021 or 2022, opening a WorldServer package is not immediately possible. What are the steps to follow to be able to open a WorldServer (*.WSXZ) package and create a WorldServer Return package?

Starting from Trados Studio 2021, the WorldServer components - which are needed to open and convert WSXZ packages, create WorldServer Return packages, and use WorldServer Translation Memories - are now included as a separate application that can be easily downloaded and installed from the App Store. The WorldServer components need to be installed once in order to be able to open WorldServer (*.WSXZ package) and their version needs to match your current version of Trados Studio.

Note: These steps do not apply to Trados Studio 2019. In this version (no longer supported), WorldServer packages can simply be opened by using the Open Package button and browse to the location where your WSXZ package is stored.

To install the correct WorldServer Component for Trados Studio 2021 and 2022, follow these steps:

1. Go to the RWS App Store. Download and unzip the WorldServerComponents.zip file that matches your Studio version. 



*Note: You can check your Studio version in the Help tab > About Trados Studio. Example:

2. Once you have downloaded the correct WorldServer component that matches your Trados Studio version, close Trados Studio

3. Unzip the WorldServer Compatibility Pack for Trados Studio.zip file that you have downloaded and double-click on the WorldServerComponents.msi file to start and finish the installation. It will finish very quickly and silently. It will also replace any earlier version that might have been previously installed on your computer.

4.  Reopen Trados Studio. In the Projects tab, you will now see a new button called Open WorldServer package. Use this button to browse to and open your WSXZ (WorldServer) package. You will also see the new button Create WorldServer Return package. You can use this button to create a WSXZ Return package once you are done with your translation.




5. Translate your WorldServer (Studio) project and when you are done, create a WorldServer Return package to be uploaded to WorldServer. To do so, on the Projects tab, you can select the project and click on the Create WorldServer Return package button. Alternatively, simply right-click on the project and select the same option:








6. The Create Return Package window will open up. Select the file(s) that you want to include in the WorldServer Return package and click Next, as in this example:




7. You will now see the option to upload your Return package directly from Trados Studio to WorldServer (option Server) or to create an actual WorldServer Return package and save it on your local computer or on a location of your choice (option File). Once you have chosen your option, click on Finish.



Important: Before creating and uploading a WorldServer Return package, to prevent possible errors that could be transferred to WorldServer

- Always run a Tag verification and create a target file for each project file. Make sure to fix any tag issues until no tag errors are found.
- Always create a target file for each of your translated files by going to File/Save target as...  If you receive an error when creating a target file, fix that error in Trados Studio before you create a Return package. Any error preventing a target file from being created in Trados Studio will prevent the Return package from being uploaded correctly and will result in an error at the Save step in WorldServer. So there must be no errors in Trados Studio before a Return package is created.

The WorldServerComponents.zip can be downloaded from the RWS Appstore
