Porting the Flex Project to CC(2014)

Hello,

I am trying to port the Flex project developed in Flash Builder 4.6 with Extension builder 2.1, to InDesign CC (2014).

As per the SDK help it mentions I can use the same environment mentioned above to port the project. But when I try it is giving error " This extension cannot be installed, it requires InDesign version in range of inclusively between 9.0 and 9.9.

Do I need to set anything before compiling the plugin for CC(2014)? Or do I need to port in some other environment? If yes where can I get the details of other environment?

Thanks for the help in advance.

Regards

Farzana.
