How to resolve the "Language Not Supported" error in HSTE

When trying to open a task in HSTE, you may receive the following error message if the language that you are trying to work with is not installed correctly on your system.

In this example, the Kurdish Sorani language may already be shown as installed in thebigword TMS Culture Management application, but the error can still persist.

Checking Which Languages are Available in Windows

To check the list of languages that are currently installed on your machine, you can follow the simple steps below:

1. Go to the Windows Search box on your Taskbar, and type PowerShell.
   
   
2. You may see one or more PowerShell applications at the top of the suggestions, as shown below:
   
   
3. If Windows PowerShell is available, select the Windows PowerShell application. 
   
   NOTE: If not available it can be installed by following the instructions here:
   https://learn.microsoft.com/en-us/powershell/scripting/install/install-powershell-on-windows?view=powershell-7.5
    
4. Once you have the PowerShell window open, copy the script below and paste to the right of the C:\Users\YourUserName> prompt. 
   
   The script you need to copy and paste is:
   
   [System.Globalization.CultureInfo]::GetCultures([System.Globalization.CultureTypes]::AllCultures) | Where-Object Name -like "*ku*"
   
   NOTE: The example script uses ku to find all Kurdish languages the system has configured. To find your language set replace the ku in the script with the task base language code, en for all English languages, fr for all French, ar for Arabic, etc.
    
5. Here's how your PowerShell window should look like after successfully pasting the script. 
   If you get a warning message after hitting paste, click "Paste anyway":
   
   
    
6. Once you press "Enter", you will see a results table, similar to the one below, listing all the language variants:
   
   
    
7. If you do not see the language variant for the task, for example Ku-SOR for Kurdish Sorani as one of the language names in the results table, you will need to: 
    
   1. Reopen thebigword TMS Culture Management application,
       
   2. Choose the option to Uninstall the required language, for example Kurdish (Sorani),
      
      
       
   3. Then choose the option to Install the required language, for example Kurdish (Sorani),
      
      
       
8. Once this is done, please re-run the PowerShell script we previously provided (in step 4) and check to see if the required task language code, for example Ku-SOR for Kurdish Sorani, is now displayed as one of the language names in the latest results table as shown below:
   
   
    
9. If the language variant that was mentioned in the body of the Language Not Supported pop-up window is displayed in your results table, then you have successfully installed the missing language and should now be able to open the task in HSTE without getting an error message.
