You create a new project.  You cannot change the source language once the project is already created.

Hi Paul,

Thank you for your reply. However, it is one of the 5 configured source languages I have to change. I never translate from French in Studio anymore, but I do translate from Norwegian in Studio. I have Studio 2017 and as far as I have been able to gauge, I cannot make that change myself by removing and re-installing Studio. 

Please advise.

Ok, you wanted to change the languages you selected when installing Studio 2017, not the source language which can only really refer to project or a translated bilingual file. 

In 2017 you are correct, you normally have to reinstall and it doesn't always work.  So the best way is to do this:

• Close Studio.
• Hold down the windows key and press R. (or right click the start/windows button and select Run).
• Paste in this:
  reg delete HKEY_CURRENT_USER\Software\Microsoft\LDSRClient5 /f
• Press ok.
• Restart Studio.

That should cause Studio to ask you for your five languages all over again and now you can select the ones you really want.

Hi Paul,

Perfect, thank you very much!
