After installing IS 2009 CD the SoundMax install wizard starts and either wants to uninstall or install and upgrade. It then prompts to restart computer. After restart nothing happens. If CD is reinserted then Sound Max install wizard shows up again and same routine follows. Installing on Windows XP with Service Pak 3. Installed IS 2009 from same disc on laptop running Vista succesfully. IS 2009 is good for 3 PC’s. Was running IS 2008 with no problems and removed before attempting to install 2009. Any ideas.
