I already have a version of TeamViewer installed. Do I need to remove it?

Yes, the current installation of all versions of TeamViewer must be removed before installing BeckmanConnect. When prompted during the removal of TeamViewer 13 to “close TeamViewer before uninstalling,” press the Retry button on the prompt instead of selecting Exit TeamViewer from the task tray icon to close the program.
