And this is probably the case when user has to accept a license on the
website.  This is URL for zip archive of yEd-3.9.1:

  http://www.yworks.com/en/products_download.php?file=yEd-3.9.1.zip

It directs to website with license text, check-box for accept and
download button.  If check-box is not set, following message is shown:

  "In order to download yEd, it is necessary that you first accept the
  license terms."

If check-box is set, client is redirected to the page with actual link to
zip archive.

Moreover, I have had email conversation with yWorks representative and
he says that installation files need to be obtained manually by the end
users from their website.
