I have connected support and they said this...Thank you for contacting us about this issue.
If you are receiving Error 36, then you are attempting to patch the game before logging into the Arc client. First, please make sure you are not logged into Neverwinter. Next open Arc, select Neverwinter, and the game should patch. Once it is done patching through Arc, you should be able to log into the game without issue. Please let us know if you have any further questions or concerns.
I don't play Neverwinter and don't have it on my drive.
I can't play STO as result of this.
