I've downloaded extensions manager 7.2.1, but it will not install. I'm on 27" (late 2013) iMac running Mavericks 10.9.5. I am the administrator of this computer.
In "help" it says to follow the instructions below before installing. In "Adobe Installers" there is no "Uninstall Adobe Extension Manager CC"
Go to the Control Panel, select Uninstall a program > Adobe Extension Manager CC, and clickUninstall.
Go to Applications > Utilities > Adobe Installers, double-click Uninstall Adobe Extension Manager CC, and follow the instructions.
EM 7.2.1 is only a patch, it can only be applied to an existing EM installation. Please use Adobe Creative Cloud client to install the latest version of EM, or install EM 7.0 GM build from Adobe - Exchange : Download the Adobe Extension Manager firstly, then apply 7.2.1 patch.
