Syncing with my Windows desktop computer has recently stopped. This function has worked very well ever since I've been a Dropbox user, until now. I also received a message that my version of Dropbox was out of date and should be updated. I selected "Update" and downloaded dropboxinstaller. exe. When I opened the installer, I received the message, "Dropbox Update installation failed with error 0xa0430722". What can I do to resume syncing with my Windows desktop computer? Thanks.
