My understanding is that EG 4.2 is supposed to provide Vista support. Tech Support won't confirm, but new releases often come out around the time of the SUGI meetings in the spring.
That said, EG 4.1 can be installed with Vista (I haven't tried it myself, but had a student succeed this fall.). Search this forum for a thread on it. If you run into trouble, SAS Tech Support won't help.
