Cannot install Less Compiler (ZXP) on Dreamweaver CC 2014! Error message states, "need version 12 and greater.

Hello,
It seems you are trying to install the zxp file into an older version of Adobe Extension Manager. Please make sure to start the Extension Manager CC and install the extension there.

Verified all versions of software, unistalled and re-installed extension manager. After re-install the extension installed but now dreamweaver does not see it as installed.

Extension Manager V7.2.1.6
Dreamweaver CC 2014.0 Build 6733
Windows 7

Also tried running the install with the DMXzone installer.

Hello,
The extension cannot be "seen" in Dreamweaver.
On saving your less file(s) it asks you if you want to compile them to css.

I may have phrased that last email incorrectly. I am trying to install the Metro UI Design Template which uses the DMXzone Less CSS Compiler. I get the error message: "This design template requires the "DMXzone Less CSS Compiler" Dreamweaver extension....." The extension is installed!!!
