error message after installation of the Dropbox desktop app

Okay, so I figured it out and found a work around. Once I downloaded Dropbox to my Mac I would select it and continually gave me an error message (which is posted above). I uninstalled and reinstalled multiple times and continued to have this issue. It wouldn't let me select anything once the error presented its self. So the work around was once it attempted to load I would click on the Dropbox symbol in menu bar and before it gave me an error I would select the preferences. It appeared that an old Dropbox account was still logged in. Therefore, I logged out and from there it allowed me to input my Dropbox details and connect my Mac to the Dropbox app. I am not sure what cause this issue but maybe the team can offer some insight. All I know is I found away around the error message and got the Dropbox app to work. Hope this helps others in the future.
