I think your system's security settings are preventing you from doing the
download. This is masked by the inaccurate message you're getting that
tells you admin rights are required. Some folks with Windows 7 found that
they had to set their firewall to allow downloads from the ADE site. They
also found that if they did, sometimes Windows 7 would not allow that to
happen anyway, because other settings inside Windows 7 counteracted the
ones the users set..... Microsoft - are you listening?
