I found a solution!
Download the zip file
Go into CFBuilder
Go to the Extensions tab at the bottom (same row the Servers are in)
Click the + button (hover text should be "Install Extension from Archive File")
browse to the zip file, click open, and tada! You have the CFC Creator.
Hope this helps!
When I created a server configuration, it added these files to the docroot already but the option wasn't availble. When I tried to follow these instructions I got an "already installed" message.
What worked for me was to click on the second electrical plug - "Import extension from folder" button and browse to the dsired extension.
