When I try to uninstall using the control panel, it keeps telling me to shut down any open LibreOffice and/or Libreoffice Quickstart programs. I do that and still get the same message.
Under windows it is possible that you have the Quickstarter installed - you will find this in your system tray - ensure that this is not loaded (if so right click and exit the quickstarter) - that is the most common reason for this problem.
I have a similar problem but I’m using Mac OS X. Any ideas?
