I know I'm not exactly the smartest when it comes to computers but I'm pretty sure that if I could run SWtOR on a phone, I probably wouldn't need to ask for help when the launcher doesn't work.
But to answer your suggestions, I just tried disabling firewalls and antivirus (I use Norton), and the launcher has not opened. I use a default HP Envy 700 PC, and I've been playing SWtOR for a few years with no problems until now. Well, a couple of problems, but nothing that isn't easily fixed. As mentioned, I have tried to reinstall the game, BitRaider included, but to no avail. In my research, I've come across people suggesting something to do with a Fix Launcher executable in the files but I do not have that available.
