Obviously, it has taken longer than 24 hours to fix, considering I have the exact same issue and have reason to believe it has to do with the serial code. Apparently, not all game advisors are aware of this issue, as the one I was on the phone with for 40 minutes yesterday never mentioned it. She did give me a new serial code but that one didn't work either.
For me, after putting the Launcher.exe in the right place and patching, I get a pop up to put in a serial code, but it has a wrong one pre-loaded. It will not except any code I put in, or the one it has pre-loaded. I hope this gets fixed soon. I bought the game Cyber Monday, downloaded it and installed it by Tuesday night, Wednesday morning I called, downloaded and installed again by Thursday night and am still disappointed. I will contact the advisors again tomorrow, and hopefully be bumped up to a Specialist who might be able to help me. I will post if I have any success.
I am also running a Windows 8 64-bit.
Edit: It turns out, they seem to have given me an old wonky version of the game. They have given me a different one and I am downloading and installing now. I will update if this fixes the issue (it should). I encourage everyone to call it in, they called me back after 30 secs and were very invested in fixing the issue.
