Hi, Following a reinstall of my system, I tried to put Diskeeper Professional back on my system. All appeared fine until I got the message: "Your system has not been modified. To complete installation at another time, please run setup again. Click finish to exit the wizard. The wizard was interrupted before Diskeeper Professional 2010 could be completely installed." Any ideas? Richard Richard Godfrey-McKay Telephone: 01738-445 880 Mobile: 07791 452 593
