I have O&O DiskImage 7 installed on my PCs. It was installed in Windows 8 and I have since upgraded to Windows 8.1. Now I am trying to remove this piece of junk and it refuses to come off. Can't repair it, can't upgrade over it to remove it. Can't delete the files. It just keeps sitting there in the tray telling me an update is available. Any suggestions? Is there an uninstall tool for this? I can't find one anywhere.
