Hi Peter,
You can determine whether Illustrator CS6 is licensed as part of the Technical Communication Suite or Creative Cloud based on the product version. Retail copies such as those included with TCS will be 16.0.x and those licensed with Creative Cloud will be 16.x (with the x being anything greater than 0). My version for example is 16.2, a Creative Cloud version. You can get the version number by going to Help>About Illustrator.
Hope that helps,
-Dave
