I have tried in the most current version of Photoshop CC, Illustrator and Inkscape.
File numbers: 126906050
I have easily been able to open other .ai files from the same contributor in the past, so something is up with these files.
We apologize for the inconvenience caused to you.
I tried downloading the same files ( #126906050 and 134421253) at my end using Illustrator CC and Photoshop and can confirm that the file (134421253) does not open in Illustrator CC and when opened in Photoshop it gives an error message " Could not complete your request because Photoshop was unable to parse the postscript", however, I did not encounter any issues while opening the file (126906050 ) in both Illustrator and Photoshop.
I would request you to try the steps mentioned below to open the file(126906050) and let me know if the issue persists.
Meanwhile, I am getting this file ID( (134421253) checked from the product team. I will update this thread once I hear from them. Appreciate your patience.
Ah, copied the wrong file number for the second one that doesn't work. It is actually 134421168
Thanks for sharing the correct file ID with us. I have already passed this concern(related to the file issues) to the product team and will be updating this thread as soon as I hear from them.
Please allow us some time.
Our product team has confirmed that the files have been uploaded in the older Illustrator formats by the contributor. Please check your email for more details.
