Sorry to hear about this @lobonz - you need to manually move the Dropbox Folder after the installation goes through and for this process to be completed unseamingly and without such conflicts or errors, I'd recommend using these steps.
After thinking about whether pressing "Cancel" should apply the "Don't show again" checkbox, the team decided against it because they don't want to confuse people by updating their settings when they click "Cancel". If you have any feedback about that, let me know and I'll forward it on to them.
I hope this information helps and keep me posted. Thanks!
I totally understand time is of essence @lobonz - sorry to hear you weren't able to move your Dropbox Folder. An advanced reinstall should fix your space errors, should you decide to move forward with this option after all.
Thanks for finding the chance to get back to me - I appreciate it. If there's anything I can do from my end to be of further assistance, do let me know and enjoy the rest of your day!
