Unable to open DWG file in Illustrator getting Unknown Error 2067

Hi there,

Sorry about the trouble you are facing. Could you please share a few more details like:

• OS and version of Illustrator installed on your system & vendor
• Is the vendor able to open the file on their system?
• Could you please share a sample DWG document with us? You can upload it to the Creative Cloud (https://helpx.adobe.com/in/creative-cloud/help/share.html) and share the download link here or via DM.
• How did you receive the files, and from where are you currently trying to open the files (Network Drive/ System HDD/ Shared Folder on System/ External HDD)?
• 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.

I will be looking forward to your response.

Thanks & Regards,

Anshul Saini

This seems to be an ongoing issue for some time, with the 2021 version (https://community.adobe.com/t5/illustrator-discussions/the-operation-cannon-complete-because-of-unknown-error-2067/td-p/11751786)
