18.5.0.125 Norton AntiVirus 2011 availability

hello,

 

my install of norton antivirus 2011 had a number of issues and with the help of tech support was removed.  after reviewing this forum, i decided to wait until the boot issue was fixed.  it seems that it is now.  can you tell me if this new 18.5 version is available in a clean download where i am asked to enter my existing product key?  the last time i tried installing norton antivirus using navdownloader.exe, it never asked me for my product key.

 

thanks!
