I'm getting a similar error to https://forums.adobe.com/message/8612177 except that it doesn't matter what I name it or put the file, it works just fine for me. The problem is that coworkers routinely get this error when trying to open files that I've touched. We've all done all the updates, uninstalled and reinstalled, the works. My coworker even sent me an XD file that worked fine for him, and then I opened it, made no changes, saved it and sent it back and it didn't work anymore. What is even happening?
What version of Adobe XD do you have, and what version of Adobe XD did your coworker use? If you are still on the "Preview 3" release, you might see this error message when trying to open a file created in the newer "Preview 4" release. (In the future you will see a clearer error message in this situation).
If you're on an older version, I'd encourage you to update to Preview 4 -- which was released about a week ago -- and see if that helps.
If not, please let us know and we can try to dig into what else might be going on.
You're totally right. They had each told me they were fully updated but when we compared release versions, I was on 0.5.6 and they were on 0.5.4.
This case is closed.
