What is your Link?
When I click download this is what appears in the URL.
The browser says it can't recognize aam://.
AAM is a link for use by the Adobe Application Manager, which is a sort of download manager/installer that Adobe uses to install the real programs.
Post the URL where you found that link.
I believe this question is regarding download of the CC version.
Also, I'm not sure what the page you linked is supposed to be,
but if anyone is looking for trial versions of CS6, look here:
CS6 Trial Download - where can I find it?
CS6 - Buy the Perpetual License version (Not Creative Cloud rental)
To buy an upgrade instead the of full version, click the buy button
then select 'I want to buy: 'Upgrade' instead of 'Full'.
CS5 and CS5.5 Products are eligible for upgrade to CS6.
