It gets part of the way, then fails to install. I can still install using the same CD on an XP machine so it is not the CD.
Civ III and Play the World installed easily and both work.
I have no plans to switch to Civ IV. Maybe Civ V if they give casual players what they took from us in IV.
Have you tried the copy all the contents of the cd to the hard drive trick?
I have no plans to migrate to Vista... so good luck.
