Illustrator error "An unknown error has occurred"

I am working in an .ai file that I have saved frequently before. Suddenly when I try to save the file, I get an error that reads "an unknown error has occurred" and the file won't save at all, anywhere. I have not seen this error message before and have had no issues opening or saving the file up until this point.

I need to have the file as an .ai file (not .eps or any other format). I am working in Illustrator CC (2015.3) and using macOS Sierra.

Hi All, Sorry to hear about this experience. In addition to the suggestions given in earlier responses, we'd recommend you to update the app to the latest version. Steps are shared here. If the issue still persist, you could check a few more things: Is the file being saved on network drive/shared folder/external HDD? If yes, try saving it locally & see if it helps. Is the issue related to a specific file? If yes, please follow the steps shared in this help article (https://helpx.adobe.com/illustrator/kb/troubleshoot-file-issues.html...

I had the same issue in win10 and noticed that when I changed all text to arial font, the file was saved. Then I changed again to the previous font (myriad pro in my case) and noticed some mullfunctioning in presenting text. So I completely removed the font, restarted the computer, started illustrator to load fonts (while the specific was missing). Then closed illustrator, installed again the font and the problem disapeared. (Note: The problem had started after I installed a 64bit version of illustrator.) Hope it helps.

Hi...I was having the same issue in CC2019...It turns out 2 linked files disappeared (??) from the layers. They were showing there via bounding boxes but were not visible. I deleted both and reapplied them. Then the entire file saved without issue...

I had the same issue and I solved it by turning off all the layers except one simple layer without any transparency set etc. and then I saved it. It went without trouble. Then I was able to save again right after that, even with other layers turned on

I have had the same problem multiple times, including work that I about to lose today, in multiple versions of Illustrator ... and yes, restarting the program clears whatever the probem is, but you lose what you were working on as only the last saved version remains. I am on Windows 10, I update religiously. I can save my file as an SVG and PDF, but NOT an ai or eps file. I do save to a remote hard drive, but also tried to my dektop and no difference.

Hi Monika. Yes I've spent the past few hours looking through and trying every solution that people suggested, not one has worked for me. To me it sounds like the 'solution' is completely random, as most people seem to find the solution by trying completely methods.

Exactly. It's a different cause for different people. If nothing helps, try and contact Customer Care. https://helpx.adobe.com/contact.html

When I get this problem saving as an .ai file, I uncheck the create pdf compatible file box and it will save it.

Thank you! This just happened to me tonight for the first time after saving the same file multiple times. I tried another suggestion to make sure layers were unlocked and visible; that had no impact. This solution (unchecking "Create PDF Compatible File" on save properties) is the only one that worked for me.

 

Running Illustrator 25.1 (64-bit) on Windows 10 Enterprise.

Hi All,

 

Sorry to hear about this experience. In addition to the suggestions given in earlier responses, we'd recommend you to update the app to the latest version. Steps are shared here.

 

If the issue still persist, you could check a few more things:

  1. Is the file being saved on network drive/shared folder/external HDD? If yes, try saving it locally & see if it helps.
  2. Is the issue related to a specific file? If yes, please follow the steps shared in this help article (https://helpx.adobe.com/illustrator/kb/troubleshoot-file-issues.html) to troubleshoot file related issues. You may also try copy-pasting the content to a new file & see if that works.

 

If nothing works, please try the suggestions given in this community post (https://community.adobe.com/t5/illustrator/resolve-slow-performance-and-unexpected-behaviors-in-illu...) & let us know how it goes.

 

Regards,

Ashutosh

This post is mostly informative to both the adobe community and developers.

Since the release of Illustrator 25.1 I've been unable to save in .ai and/or .eps on my local disk (HDD/SDD), so I've been forced to save everything in Adobve ccloud (.aic).

However, I recently seemed to find the issue: when choosing .ai/.eps as saving formats, I am forced to unlock and make ALL layers visible in order to be able to save on ANY local disk. Otherwise, it will throw the famous "An unknown error has occurred".

 

Hope this helps.

Hi! Same thing happens to me!

 

Some files I have been working on and saving for days without problem and suddenly the "an unknown error message has ocurred" pops up (maybe 10 minutes after successfully saving the file) and from there on I'm unable to save/save as the file. I have to take everything to Photoshop, paste as intelligent object, close & open illustrator, open the intelligent object, take it to a new file and then save it. This is a real pain and unacceptable, as it renders the working process unefficient and makes me lose work constantly. Sometimes the same problem file later on will open and save without issues again, sometimes the error persists, it's a real lottery.

Illustrator 25.1

Mac Os 10.15.7

No hidden/blocked layers or objects (sometimes it's the simplest vector file with only 1 layer)

Ocurrs with local disks and external hard drives

 

I really hope somebody at Adobe takes this issue seriously - as I can see looking at the forum there are posts from as far back as 2014 without viable solutions given.

I solved this issue by freeing up space on my HD. I was working with a 500mb file and did not have enough space to save the changes I made to the file.

 

Try emptying the trash and remove large files you no longer need.
