When I try to install the Toolkit for CreateJS using Adobe Extension Manager CC, the following error massage appear 1/3 the way thru the download "Adobe Extension Manger CC This extension can not be installed, it requires Flash version in range of exclusively between 12 to 12"
PC Windows 7
The trial version of Flash CC 2014 downloaded OK
Moving this discussion to the Extension Manager forum.
You don't have to install it. Toolkit for CreateJS has been integrated into Flash CC. You can find it under "Window" dropdown menu.
