Never. How do you even arrive at such an assumption?
Apparently i was misinformed. When I decided to transfer CS5 to my new machine I noticed that Illustrator was not there so I decided to ask the experts.
Thanks for your response.
If you had the full Creative Suite 5 - then that would have included Illustrator and a lot more.
If you just have Photoshop CS5 - well, that just includes Photoshop and Bridge.
