Install Probem configuring SolidWorks

When installing SolidWorks on one workstation, it installsfine, but when opening SolidWorks the Windows Installer pops upsaying " Please wait while Windows configures SolidWorks".Eventually SolidWorks will open, but this happens on every open. Itonly happens on this machine. The user has Administrator rights. Itseems that it must not be registered correctly. Uninstalling andreinstalling do not help. Any thoughts would be greatlyappreciated.SolidworksAdministration
