Frank,
Generally speaking, all the HPS games will run under VISTA, but there are some specific steps that must be taken. Chief among them is to NOT install them in the "Program" folder. Instead, you should install them in a separate folder, e.g., C:/HPS/Campaign X.
The Talonsoft BG games, however, will not run under VISTA
. If you still want to play them, you'll have to purchase the revised versions published by Matrix games last year.Drop me a line and tell me which games you are having trouble installing.
