Greetings Raina_Que,
Please go to www.swtor.com/download, download the latest launcher setup file and run the setup over the current installation. After this please remove and re-add firewall and antivirus exceptions for SWTOR.exe and Launcher.exe.
Then, ensuring that you have the launcher closed and gone from your Processes list in Task Manager, delete the following files:
- "Patch" folder
- "Patcher_-1toXX" or similar folders
- "assets_swtor_XXX_XXX" or similar folders (do not delete the folder named "Assets")
- "Patcher.version" file
- "Launcher.settings" file
- "Launcher.exe" file
Then run the Fixlauncher.exe found in the client installation folder.
Once this has completed, please restart your computer in Safe Mode with Networking, and let it patch.
Thanks for your patience.
