I have an old Mac incapable of running Yosemite. So it is running 1Password version 3.8.22 which, when I check for updates it insists is the latest version.
I have a new Mac running 1Pasword 5.1.
I want to move the agilekeychain from the old machine to Dropbox so I can use it with the new computer. I go to Preferences > General > Data File > Move to Dropbox and press the button, and I get the error message "Dropbox is not installed", but Dropbox is installed on that machine and working perfectly. I have no idea how to proceed!
