Another gotcha (not sure if it's been mentioned before), but there are some tricks to getting PDFCreator installed on vista as well, if you need it for BookDesigner. The installer won't run (complains about not being compatible with the version of windows), however if you right click on the installer and set the compatibility mode for Windows XP, everything should be fine.
Also, there are lots of comments on the PDFCreator forums about the client mode (which is what BookDesigner needs) not working on vista. Don't worry about it. You don't actually need to be able to launch PDFCreator manually, so it doesn't matter if it won't run on vista. BookDesigner just needs the files present (probably uses some libraries that are part of PDFCreator), you don't actually need PDFCreator itself to run.
The forums say that if you need PDFCreator to run on vista then you should install it in server mode. Don't do that, BookDesigner needs the client install. Been there, done that, had to start over.
