I have the same exact problem as well, with the same setup: Windows 8 Pro, Office 2010, and uses Office 365. I ran the Microsoft Office 365 desktop setup several times, restart, and still cannot solve the problem. Every time when the upload failed, the upload center would show the error massage that says "Upload Failed Your changes were saved but could not be uploaded because of an error. You may be able to upload this file using the server Web page."
