IMPORTANT NOTICE:
Extension Manager obsolete in CC2015 ALL Creative Cloud users should move to the Creative Cloud Desktop application to install Add-ons. 2015 users MUST use the Creative Cloud Desktop application to install Add-ons. It is still possible for earlier Creative Cloud versions (CC and CC2014) to use Extension Manager CC, but we STRONGLY RECOMMEND that you migrate to the new model. |
