It's not a question of the link, it's a question of than your code don't return a valid string on my computer.
A other problem is your method to get the dowload folder : "%HOMEDRIVE%%HOMEPATH% is the same of %USERPROFILE% and your code don't works if a user had moved the Download folder on other hard drive.
Apparently we can't use "Knowfolder" with JScript for get the Absolute PATH of Download or Movie folder..
