Launcher won't update

sorry for the delay on my response, I got caught up in stuff.  anyway, here are some steps that you can try:

Make sure launcher.exe and swtor.exe are in your anti-virus / firewall safe list.

One weird thing that someone had happen was that after they unistalled swtor, they would reinstall but the icon on their windows screen was the old icon from before it was uninstalled.  Once you have the launcher installed, remove any old icons first then go into the swtor directory and place the launcher.exe icon back on your screen and run that from there.

If it still won't patch,

1. Run the launcher and log in.
2. Open the task manager on your computer (shortcut is Ctrl+Shift+Esc).
3. Select the Processes tab. On Windows 7, sort by image name and look for any starting with "br", they should be listed as belonging to Bitraider in the description column. In Windows 8.1, scroll down to the Background Processes and look for any Bitraider listings. Right click and end them. Don't worry if they come back.
4. Select the Services tab. In Windows 7, click on the button in the lower right corner that says Services. In 8.1, click the link at the bottom that says Open Services.
5. In the Services window, sort the list by the Name column, and look for BitRaider Mini-Support Service. Right click on it and select properties.
6. On the General tab, about halfway down, there should be a dropdown menu that says Startup type. Make sure it is set to "Automatic". Hit Apply the OK.
7. Close the Services window, the task manager, and the game launcher. Then restart the entire computer.
8. When computer has restarted, run the launcher and log in. The download process should now start properly.

If that doesn't work, you can also try running a repair:

Non-Streaming launcher - Log into the launcher but don't click Play. Check for small letters "ST" in the bottom left corner. If this is NOT present, click the cog icon and then run the repair option.

Streaming launcher - If the letters "ST" is present, close the launcher, right mouse click on the game shortcut, select open file location and delete the BitRaider folder. Then start the launcher.

Worse case scenario switch to the non streaming launcher:

NOTE this is a complete download of the game again

right mouse click on game shortcut and select open file location

open the launcher.settings file in notepad and locate the below line and edit to the below

, "PatchingMode": "{ \"swtor\": \"SSN\" }"
, "bitraider_disable": true

SAVE the changes.
Delete the BitRaider, Movie and Asset folders then start the launcher.

Hope one of these options works for you.
