Windows 2003 server SP2, IE8, preinstall apps have been run, also Virtual Technician which cleaned up old installation. Attempting to re-intall because the auto DAT updates stopped for no apparent reason. When attempting to install, the prompt "installation may take a few minutes, etc) pops up for about 10 seconds and disappears. Nothing installs. :confused: Tried adjusting internet options to no avail. Tried with and without proxy server. Any ideas??
