[Lucy28570325pmsm]

I can't seem to use image trace in illustrator - I get the following message. "the operation cannot complete
because of unknown error (UKCO)" 

Does anyone have any idea, thanks in advance.

Yes, Image Trace is broken in the 27.3 update.

You can revert to the previous version by clicking the 3 dots after Illustrator in the all apps section of the CC app.

I  had exactly the same problem. I just downgraded my illustrator as Ton suggested, and it worked.  Wish the latest version works as we all pay for it monthly.

After the latest update Adobe Illustrator update Image Trace will not work!!! Everytime I try it says "The operation cannot complete because of an unknown error [UKCO]". I've tried changing the name of the UXP folder, and extensions folder and it hasn't helped. I've restarted computer and app several times with no success. 

How come Adobe offers NO support when I'm paying $$$ per month than ever? There's nobody to help when the program that was working yesterday won't work after their 'update'. NOT IMPRESSED. 

Image Trace is something I use almost DAILY, how do I function my business when it's not working, and the workarounds don't work?? 

[Ton Frederiks]

Unfortunately the only workaround is to install a previous version using the CC app.

Also when I click the PREVIEW in it it throws this error window:

[rockettemedia]

Image Trace improved??? After the latest update I can't even USE Image Trace, it just says "Operation cannot complete because of an unknown error [UKCO]" NOT impressed that you made my program WORSE, a tool that I use daily is not even available anymore. 

[STUDIOLGLR]

I have the exact same problem, I had to roll back to the previous version, the error code is different, I am currently located in Mexico, maybe it is location based? this is a serious bug.

[Ton Frederiks]

No, it is not location based, I had [EnNS] as well as [UCKO], currently the only option is to install the previous version.

Hi All, @Lucy28570325pmsm @leslieb8922941 @Rio28590561ut8t @Ton Frederiks @STUDIOLGLR @rockettemedia @eduardosalvador

Thank you all for bringing this issue to our attention. I have checked with our product team regarding the unknown error codes [UKCO] and [EnNS], and they are aware of the issue and currently working on a fix.

In order to better understand the issue, would you all mind providing us with more information, such as:

• Does the issue occur with files created from earlier versions of Illustrator?
• Are there any image-traced objects present in the affected files?
• Are you attempting to retrace an object that has already been traced?

Your cooperation in providing us with this information would be greatly appreciated as we work towards resolving this issue.

If you have any further questions or concerns, please do not hesitate to reach out to us.

Thank you for your patience and understanding.

Best,

Anshul Saini

Hi @Anshul_Saini ,

Does the issue occur with files created from earlier versions of Illustrator?

No, new files with freshly placed images (linked or embedded)

Are there any image-traced objects present in the affected files?

No, empty new files

Are you attempting to retrace an object that has already been traced?

No, first click on Image Trace

These errors did not happen in prerelease builds, just started after updating the installed version.

When the [UKCO] error appears and you click OK, you have 2 choices in the following dialog: The object "Image Tracing" is not currently available > Continue or Stop.

Both options will trace anyway but give different trace results. Although they give the following error after a while: The operation cannot complete because of an unknown error [EnNS]

[AnneRenata]

I am having the exact same problems after the new update and image trace is now unusable, so frustrating. This is happening with brand new files, a couple of times I manage to get it to work, but the quality is bad, the presets don't work and the resulting image is unusable. My image is fairly simple too, just a black and white line drawing. I will follow the suggestions and revert to the earlier version of Illustrator and hope that works.

[Melissa Capitani]

Also when I load a newly created pdf (simple black and white drawing) into photoshop and try to do automatic recalculation, it gives me ukco error.

[Harmonious_Cascade5E82]

Same problem here. UKCO error on an AI file created in a previous version when using image tracing.

[Anshul_Saini]

3. Accept the Prerelease agreement.
4. Install the Prerelease build v27.3.1_629 by closing Illustrator and going to the Creative Cloud Desktop app > Prerelease section under apps > click on install. Please note that this will not replace the existing installation of the Release build of Illustrator.

[SindySinn]

Agreed... my Live Trace has also died. 

Installing the previous version as we speak.
Of all the tools to test, Live Trace is the only one I care about.

[cornelis_bos]

I have the same issue

[Ton Frederiks · Accepted solution]

There was an update today to 27.3.1 (check regularely, maybe not yet everywhere available), that fixed the Image Trace problem for me.

[peterk6392879 · Accepted solution]

Yes - Live trace (Bildnachzeichner) in german version 27.3.1 is also working again! (mac)

[Anshul_Saini · Accepted solution]

Great news! We're thrilled to hear that the issue with Image Trace has been resolved with the latest update, v27.3.1. Thank you, @Ton Frederiks and @peterk6392879, for taking the time to install the update and confirming that everything is working smoothly again.

We encourage all users to update to the latest version and to let me or @Anubhav M know if they continue to experience any issues.

Best,
Anshul Saini

[eduardosalvador]

is everything else good too?
should we update to that now, or better wait and stay in 27.2?
