Illustrator issue

Hello there.

Does anyone use Adobe Illustrator graphics editor? I have installed it for openening ai format file which was e-mailed to me. But I get the following error, “The illustration contains an incomplete or garbed object description”.
What’s wrong? How to open ai file?

Are you trying to use illustrator or unity?

You can to view the file using any AI viewer. For examle:
Inkscape
GIMP
AI Open File Tool
CorelDraw
