I assume you're asking for a download link to Flash Pro which was replaced by Adobe Animate CC. You can try the links below but I don't know if this will work with your license. Also follow the VERY IMPORTANT INSTRUCTIONS.
That said, there are better apps for making vector graphics. Illustrator is one. Inkscape is another.
Flash based content is dead because as John said, Flash Player (necessary to view Flash) is end of life now. Even if you could find Flash player which is unlikely, most browsers and operating systems won't allow it to launch for security reasons.
Hope that helps.
