Please note that the remainder of the post appears currently helpful and I would like to thank the poster. https://answers.ea.com/t5/Troubleshooting-Guides-Info/Guide-How-to-Switch-to-Non-Streaming-Launcher/td-p/4867417 apparently duplicated http://www.swtor.com/community/showthread.php?t=673714 state: "if you have the old version still on another computer , copy all the game folders over to this computer," but doing so appears only to wear the drive.
