This much I've learned about installing my new friend Adventus Piano Suite Premier, and that is, for Vista 32 SP2, anyway, don't try to do it from the auto-run thingummy that pops up. Instead, go onto the CD and right click on the set up program, and then run as admin. And then it seemed to work, (after several abortive attempts to install it from the auto run). But I don't know if it's really working, yet, because now the keyboard software has gone kaput and PSP can't read it. So now I'm trying the umpteenth reinstall of that.
