I have been investigating this for a couple of days and I can't find an answer. I licensed Extension Builder 2 and am a Creative Cloud subscriber. My ideal scenario is to build my extension with Fb 4.7. However that seems an unsupported configuration so....


My second best option is to build with 4.6:

     I install CS Extension Builder 2.0 into FlashBuilder 4.6.

     Install seems to complete.

     I build a simple helloworld project.

      I target for CS 6.

     I select Run As Adobe Indesign Extension

I get the error: Unknown Flex SDK: "Extension Builder 4.5"

Sure enough, my project is targeting "Extension Builder 4.5" but this SDK is not installed. Or not recognized. Or...


Please help. I have encountered this on two separate machines (both mac os 10.8.3) and I am stumped.
