I was using a Mac, and saving things in a dropbox folder, this worked great with ios version and mac version. Now using Windows instead of Mac. When I got to open project I get dialogue "created using a new version check for updates..." Exact dialog attached.
I check for updates, it says I am up to date. Thoughts on this?
Which Windows Scrivener version are you using now, and what was your Scrivener Mac version? If you were using Scrivener 3.x on Mac, you'll need to go back to Mac and export those projects to Scrivener 2 before you can open them in Windows. If you were using Mac 2.8.x.x, then it sounds like your Windows version is old despite what "Check for Updates..." is telling you. You'll need Windows v. 1.9.7 to work with iOS compatible projects.
So you know where I'm coming from:
