The Titanium client refuses to download on my computer via the discs, always got an error.
I have the same issue. I have 2 towers and a laptop none of which would install after second disc getting an error. I actually own the discs they are not rips. I had to use a friends computer to install it then copy paste over. All computers are windows 7 64bit. With different processors, hard drive, MB and optical drives. So no idea why it failed.
