Hey everyone, after updating to the newest version of Illustrator, I can't work with it anymore. As soon as I click on it, it loads as usual, but then it shows me this "The operation cannot complete because of an unknown error" message. After I click "Okay", Illustrator opens, but it doesn't show anything besides the menu and I can't even open a new file or anything else, which means I can't use it anymore. Please help.
Hi. Does your system meet the minimum requirements? If you could share some of your specs it would help us to diagnose the problem. Things we'd need to know include: Operating system (and specific version), Type of machine, amount of installed RAM, type of graphics card. 🙂
You can find the minimum requirements here:
If you meet the minimum requirements, then your prefs may have become corrupted. You can reset them following here:
Also restart your computer and make sure the Adobe Cloud is up and running. That can clear up corruption in the cache.
The same with me, nothing helps. * Illustrator 24.2.3
Reset preferens, competently wipe with AdobeCreativeCloudCleanerTool, error is always repeated.
For me, the error is in the previous versions as well.
Win 10 Pro 2004 (10.0.19041)
NVIDIA Quadro P4200 - driver ver. 452.06
Maybe it can help: in C:\Users\xxxxxxAppData\Roaming\Adobe\Adobe Illustrator 24 Settings\en_US\x64
24.2.3.CrashModule\ Fault: AIUXPExtensionHostAPI.dll
I was also facing the same problem, but it was fixed by renaming the folder. Please follow following steps
Go to following locations and rename "extentions" to "extensions_old"
Windows: Program files /common files /Adobe /UXP /extensions
MAC: /library > application support > Adobe > UXP > extensions.
I hope this works for you as well.
Yes it works, thank you so much for your help.
Thank you so much, sir. It really worked this way.
OMG! You can't imagine how long I was dealing with this trouble. Even the Adobe Support had declined haha, they said the only solution was to use an older version of Illustrator.
This worked perfectly.
Thank you so much! 😄
I would like to award you the highest honor I can bestow.
It's works...... nice tips
Thank you for your advice, I tried many ways, including re-install software about 4 times and finally your solution worked for me. Thank you again.
Hello i got the same problem. But i had to download Microsoft Visual C++ from 2008 to 2017, after that i restarted my computer and now it fully working.
your solution worked fine thank you i appreciate your help.
Thank you so much. your article help me.
Just for anyone else who still needs a solution - your canvas size might also be too large.
If you can, make it as small as you can afford to.
I tried all the suggestions here, then changed my canvas size and making it smaller fixed the issue for me
Configuration: iMacPro (2017) running macOS Big Sur v11.5. Illustrator v. 25.3.1.
I created an illustraton that I need to rotate/revolve as a group. The moment I hit either the Revolve or Rotate command, I get the error "The operation cannot complete because of an unknown error.[CANT]. I press OK and i get the 3D revolve spec window. With Preview clicked, the moment I try to change any properties, the error reemerges. My artboard is only about 15" x 12". Changing the size doesn't seem to do anything even if i make it 1 x 1.
