I have been trying to downgrade back to Adobe Flash CS6 adn have not found a way to do so with the new Creative Cloud. I have enabled "show older apps" and it has done nothing if anyone knows the awnser let me know.
The answer is NO.
If you want to use CS6, you have to find a standalone copy. Some are sold on ebay.
Adobe has changed things so you are only allowed to have the current latest version, and the one previous version. So unless you have an old copy with a license, its probably not possible .... at least not from Adobe's website.
