I have had AI for many years now, but suddenly this morning I get this message when trying to open-up AI, which I need for my business. I have tried uninstalling and reinstalling. I have tried system restore. Nothing. Please help.

Hi Tracy,

Sorry to hear about the trouble you are facing with Illustrator while launching it. In addition to the information asked by Monika, I would request if you can share a few more details like: 

1. Do you have a default printer set? If not, please set it as Adobe PDF and please launch Illustrator and see if it works.
2. Screenshot of the error.
3. Does it generate any crash report? If yes, please submit the crash report by following these steps: https://helpx.adobe.com/in/illustrator/kb/crash-next-steps.html
4. When did this start happening? Are there any recent changes made to your system? For example, any antivirus, system updates or web extensions installed recently.
5. If you are using Windows, please share the Event Viewer Logs, please refer to the screenshot below:

Looking forward for your response.

Regards

Rishabh - This fixed it! Thank you so much! Somehow my printers were all deleted after the last MS Update.

Glad to hear it has been resolved! Feel free to reach out if you need any help in the future. Thanks!

So what was the fix?

I'm having this problem and I don't see any procedure to follow to correct the issue short of setting default printer to Adobe PDF - I do not have that as a printer choice so is there any other information about things we might try?  It used to work just fine and then yesterday it comes up with this error when you launch it and it just quits.

Hi there,

Sorry to hear about your experience. Would you mind sharing version of OS & Illustrator? You may also try resetting the preferences. Please follow this help article and let us know how it goes.

**Please note that resetting preferences will remove all the custom settings and Illustrator will launch with default settings. You can also take a backup of the folders in case you want to. Location is mentioned in the article. 

Regards,

I have a printer set on default already and the article was not helpful. How am I suppose to change the preference if I cant get the app to open? 

[#10]

nvm I got it working thanks

[#11]

How did you fix it? Please tell me I've been facing the same problem since two days. My illustrator won't open and I have no clue how to check if printer is set on default or not.

Hello,

Since this morning, my Illustrator runs into this error too. I've tried all the previous things, like setting my default printer to Adobe PDF, resetting prefs manually, but it does not help. I've deleted my version (25.0) and tried to run the previous one (24.3), which still works fine. Updating that version again does not help either. What should I try to fix it?

[#13]

I've fixed it! What I did was remove all folders related to Illustrator 2021 (in %appdata%, program files etc.) and after that, fresh installation of version 25. I did make sure to back up all my folders and preferences, but since I could update from my already installed version 24.3 that proved unnecessary. I hope this helps someone!
