I have Flash Builder Premium version 4.7 with the Adobe Creative Cloud on Windows.
I will not tell you how to hack it with a certain .dll in a certain place (at your own risk)
My account is maximized by creating HTMl5 ads and I use a lot of Photoshop and Illustrator for projetcts. I also do drone footage so I have After Effects and Media encoder. To see Flash Builder in creative cloud turn on Show Older Apps in your account Preferences and go to APPs and scroll down. You should see the toggle option.
