Found this little nugget in the installlog.txt while downloading Titanfall 2
"09:27:22 Setting up uninstall data ...
09:27:22 ERROR: Failed to copy C:\Program Files\EA Games\Titanfall2\__Installer\Cleanup.exe to C:\Program Files\Common Files\EAInstaller\Titanfall2\Cleanup.exe.
09:27:22 Failed to install cleanup program
09:27:22 Installer finished with exit code: 2

I manually copied the cleanup.exe and cleanup.dat in to the folder it attempted to copy it into. Looks to be an access issue with windows. EA desktop isn't requesting the rights to copy to folder and needs admin approval (even if you run desktop in admin mode it won't request access).
Long story short, just do the copy for the damn launcher and see if that works.
