I am attempting to open an .aix (Adobe Illustrator Exchange) file exported from ArcGIS Pro into Illustrator CC (24.2.3) Illustrator is telling me that it is an unknown format and cannot be opened. I don't even see .aix as an available file format in the "open" window. I have the ArcGIS Maps for Creative Cloud extension installed and am signed in to the ArcGIS Online account that I administer.
Can anyone help me figure out how to use this?
