On the root level of the hard drive (where the readme file is) there is also a small Setup.exe file. That is the main hard drive Setup file, and that is what the readme is talking about. Do you see that file there? If not, it's possible that an anti-virus program on your computer quarantined it due to a false positive, that's happened in the past. If that's the case please do let us know so we can get it resolved.

That said, you CAN just run the bandinabox_realband setup file like you are doing. That is essentially equivalent to the "custom" install that the readme talks about. The main setup just points to this file.
