I'm using Illustrator CS6 (Mac) and I need to save some files to CS5.5, but this doesn't appear to be an option in the Save As dialog. When I choose Save As, I'm given Adobe Illustrator as an option (along with PDF, EPS, and a few others), but it isn't version-specific. This contrasts with, for example, Flash CS6, where my format options are clearly marked as CS6 or CS5.5. Am I missing something? Is there not a way to do this?
I think you are not proceeding further from the Save as Dialog box .
Here is the link that will help , the link states CS3 and CS2 but it is same for downsaving the file to old illustrator version
Blew that one all to hell. In AI you will need to use Save As and give the file a name and make sure that the file type is set to AI (dropdown list below the naming window. When you hit the save button a new dialog will come up with a dropdown list at the top where you can choose your version of AI.
