I also just bought a new computer running windows 11. Launcher wouldn't work. My corrective action was to copy the files from my old hard drive SWToR directory into the new SWToR directory on the new hard drive. I then created a shortcut from the copied launcher file top the desktop. Seems to working fine so far. I pulled the hard drive out of old machine and connected to new machine via a hard drive drive docking station. Would probably work using a thumb drive, if you have one big enough.
