Adobe Illustrator - not opening after update 25.2.3

[Roxanne5FF1]

Just did the update for Illustrator - not opening after update 25.2.3
I have the iMac late 2015 any suggestion?

If you didn't do that already:

- try and reboot the computer

- try and reset the preferences (rename the folder, so it's not permanent, because it will nuke all your settings)

rename which folder?

[Monika Gause]

The preferences folder is in your user folder on your system. Please see exact location here: https://www.vektorgarten.de/illustrator-settings.html

Hi Roxanne,

Sorry to hear about your experience. Would you mind sharing the version of the OS & Illustrator? Did resetting preferences as suggested by Monika in earlier response help?

In addition to that, I'd request you to try the suggestions given on this community post(https://community.adobe.com/t5/illustrator/resolve-slow-performance-and-unexpected-behaviors-in-illu...) & let us know if they help.

Regards,

Ashutosh

There are a couple of ways to reset your prefs, for this one I recommend a longer but more thorough method.

Reset PrefsThoroughly (Mac)

• Quit Illustrator (100% you must do this)
• Finder >> Go (hold down option to show hidden) >> library 
• Preferences >> Adobe  >> (Program Name) rename to (Program Name) .old
• Library- >> Caches >> com.(Program Name) rename to (Program Name) .old
• Library >> Application Support >> Adobe >> (Program Name) rename to (Program Name) .old
