Can't install - Oops at step three
it was 'table already exists' and now I understand. When I first ran the installation I had guessed at the user's db priveleges (based on another CMS) as I couldnt find the Craft ones at the time. So that created the table but with the wrong privileges. Each time I subsequently ran it, it failed as the table already existed. – a1mark Oct 22 at 8:48
