I didnt pick up on the double graphics cards/Cd-rom drives since some machines actualy do have that. and the CD aliases etc are correct for an SoA only installation, which is what you have at this point.

The double graphics card etc could just be ghosts from before an upgrade. Go to my computer->control panel-> system and remove the older ones. Check if you actualy do have two graphic cards first though, or you'll end up installing drivers all over again. While they might not be causing your current problem, They will be slowing down your machine and might cause problems later.

When you say cant install ToB, do you mean its comes up with play and refuses to let you install it (try running the setup program on the ToB cd directly), or does it give an error. I dont think the no-cd causes this, but ToB does replace your exe so youd need to get a new one patch anyway, since the SoA patch does not work for ToB.

Anyway, when an install gets seriously screwed like this, its often best to backup your saves, uninstall it and delete the directory, thus removing as much of it as possible, and preventing something in the override directory sticking around and causing hassle later.
Then you can re-install from scratch, and maybe it'll work again.

you could also try scanning for a virus, they can cause all kinds of errors, although i havent heard of one doing this.
