Joe,
The laptop says AMD 64 mobile technology. So far I have set Internet security to default, disabled windows firewall, and tried to reinstall Windows installer package from Microsoft site which did not complete its install popping an error message saying exactly that. I them checked the registry for any errors but the file was empty.
Some setting appears to prevent any download to install and the messages are all for not being able to write to or access a file whether I' m in Explorer and Firefox. Possible insufficient access is also mentioned.
