Dropboxcleanup.exe has stopped working - Windows 8.1

Thank you for reporting this issue to us. The engineering team understands the problem and is working on getting a fix deployed. An automatic update that resolves the issues will be installed soon.

So far, we've only seen the problem affecting Windows users on Windows versions 8.1 and earlier who installed Dropbox without administrator privileges. In the meantime, here are 2 different workarounds which will silence the error message from appearing

• Option (1) Delete the problematic DropboxCleanup.exe file. This application is not needed for Dropbox on these versions of Windows and deleting it will not cause problems.
  • Open file explorer, and enter %LocalAppData%\Dropbox\Update\1.3.733.1\ in the address bar.
  • Click on the DropboxCleanup.exe and delete it
  • Demo here
• Option (2) Reinstall Dropbox with administrator privileges
  • Process is described in this document. With administrator privileges enabled, the error should stop appearing.
