Same issue. Stuck at 37% though. Followed the instructions below. Same again.
It might help to remove and re-add the game and launcher to your firewall and anti-virus exceptions lists, as your existing software might not like the updated files, and may be blocking them as you try to install.
If this has no effect, next you can check to discount/point to a 3rd party program. Also, even when ostensibly disabled, some antiviruses will continue to interfere with programs, so this is a way to ensure their presence isn't a factor. To do so, restart the computer in Safe Mode with Networking (it's possible on 8, but a little more involved than previously.) and then try to patch up.
If it freezes again while patching, close the launcher, navigate to the game folder and delete any of the following files, if present:
- "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 a copy of the setup file over your existing install. You can get the file from here
and it's a good idea to get a copy of this before swapping to safe mode.
I hope this helps.
