Windows XP with all service packs installed. NAV 2006 hangs just after installation starts. I have removed all Symantec products using their uninstall program "SymNRT", removed temp files, started in selctive mode with only necessary programs loaded and followed all (Not many) suggestions on the Symantec site. I am unable to check for viruses as the previous NAV 2005 was removed. Any ideas or suggestions.
