You still haven't answered my question. Which version of CS6 do you have?
The version you have matters. Cloud software 12.2 received updates for HTML5 and CSS3 that perpetual licensed ver 12.0 did not. CS6 is not being updated anymore.
The HTML5 pack was introduced with CS5. I think that the HTML5 pack was discontinued after CS5.5 came out.
