Yes it will run fine. I currently have Illustrator 10, CS, CS2, CS3 and CS4 all installed and running in OS10.4.11.
Isn't the trouble that the installer won't run though? Or is that illy 9?
Thanks so much.
I will now run my Ill 10 on 10.4
Jeseham is correct. The AI10 installer won't run. You need to copy AI10 from a previous installation.
