The original NAV 2003 personal version, today ordered service expired, so uninstalling a personal version, ready to reload one. Who knows that the original installer can't find it, so I copied a NAV Enterprise version on the document server of the previous project group (our customers provided), and then discovered that it became an acceptable client, various permissions They have been locked by the administrator, and the administrator password is also transferred. It is a virtue with our company to break the office scan. The dead administrator has set up a few Friday scan hard drives to search for several registry, finally find hkey_local_machine / Software / Intel / Landesk / VirusProtect6 / CurrentVersion / There is a bunch of relevant nutriments, tried several, found VPuserunistall, changed to 1, uninstall, no longer ask me to password.
