Model Name:iMac / Processor Name:Intel Core 2 Duo / Memory:4 GB When I installed Illustrator CS3 at the first time, I didn't complete it and closed it. While I installed it again, it said "Adobe Illustrator CS3 cannot be installed because it conflicts with Adobe Illustrator CS3". I was be stopped on this step, so I deleted the Illustrator CS3 from Applications/Utilities/Adobe Installers without clicking it to uninstall. And I deleted other Illustrator CS3 files. After that, I tried to reinstall Illustrator CS3 again, but it kept to say "Adobe Illustrator CS3 cannot be installed because it conflicts with Adobe Illustrator CS3". I cannot find any Illustrator in my MAC. What is wrong? How can I install Illustrator again? Should I format the computer and install all the applications again?
