I have completely reinstalled Origin from scratch, gave it a custom download location, gave it custom download locations both for game downloads AND for everything that normally goes in the Program Data folder, AND I have over 550GB of free space on my hard drive, yet Dead Space 3 + Awakened DLC (a little over 10GB according to Origin) still won't install past 23% claiming I've run out of space. I've done everything that everyone else has suggested to try, but now not only can I not even REINSTALL Dead Space 3 (it was already installed before this), but I've managed to reinstall Sims 4 + all my DLCs for it which is 14.73GB according to Origin, which PROVES I had enough space to download, just Origin refuses to download for Dead Space 3 for some reason.
Edit: Nope, APPARENTLY it only refuses to download past 23% if I try downloading Dead Space 3 AND Awakened DLC at the same time. I just installed Dead Space 3 successfully again, but it yet again says I'm out of space if I try downloading Awakened. Clearly it's a bug with the Awakened DLC, and EA either needs to patch it or give me my money back because they sold me a useless defective software that won't even download.
