Hi I have 15.7 up and running on XP64. I have had no issues. The install went smoothly as well. One thing I will say is I was disappointed in the performance. I was hoping it would be faster but if it is , not by much. Allegro is still a 32 bit application. Because of this it can't take advantage of the larger memory space of the 64 bit OS.
