I purchased a retail, boxed copy of NAV 2009 a couple years ago, and have since renewed it twice. In 2009, after renewing, I got an email that an update was available, and downloaded a file called NAV10UPEN.exe to upgrade it to NAV 2010.
Earlier this year, I renewed it again, and later received an update called NAV-UPGRADE-ESD-NoDefs-18-1-0-37-EN.exe to upgrade it to NAV 2011.
I will be rebuilding my computer this weekend (moving to Windows 7), and was looking for a full installer of NAV 2011. I found a file called NAV-ESD-18-1-0-37-EN.exe on Symantec's site, and was wondering if I can use this installer with my original product key from NAV 2009. My NAV 2009 product key is the same as the one that's showing under Products on the Norton Account site.
