Hi Ana Johnston, thank you for posting your issue. May I know where you encountered "Error 72"? If you can provide a video or a screenshot of it, that would be very helpful, and we would appreciate more information on what you have been doing or what software and buttons you've clicked that lead you to see this error.
If you are referring to the Error 72 in Adobe, it means that the Adobe installer was unable to copy a critical file or directory so try installing it again. You can contact Adobe Support to be assisted further.
I look forward to your reply.
