Illustrator preferences and other tool bars won't upload and when I try to exit the program, it always pops up unknown error
Is this a fresh installed version?
Can you try and reset the preferences? This will erase all your settings. https://helpx.adobe.com/illustrator/using/setting-preferences.html
Did you already click on the "More Infos" link in the error window? What does it say?
it said mulltiple things like update drivers
ok, it worked thank you
Good to hear that it worked. Can you perhaps tell us what exactly could solve it? That would help other people who have the same issue.
