I am trying to install a trial version of Dreamweaver CS6 using the Adobe Download Asisstant. I am able to download the .dmg file and open. I am able to start the installer, enter my adobe user name and password, then I am prompted to enter my proxy user name and password. After entering my proxy user name and password (correctly!), I receive an error message that says "Proxy Password: Unable to authenticate user. Please check the user name and password and try again". So, after numberous attempts, restarted, checked with IT about user name and password (confirmed correct), network and internet are working correctly, and we have turned off my firewall for my IP address AND still not able to get past this proxy password error message. I have even tried deleting the .dmg dreamweaver file and re-downloading, but still unsuccessful. Can anyone help me?
