Installer error despite supported Photoshop version« Back to Questions List

I have Photoshop CC 14.2 which is supposed to be supported by the CS6 installation - however when I run the zxp file for CS6 it gives me an error that "this extension cannot be installed. It requires Photoshop in the range 13 to 14.9". Is there a fix / workaround? Thanks

Correct Answer

Thanks to another user we were able to track down the root of this issue.

You can install CS5 or CS6 versions of Export Kit on your system. The problem you have is that you are using Extension Manager CS6 to install a CC extension.


Open Extension Manager CC (Or the version of Adobe you you wish to install) and install the plugin normally.

Extension Manager CC

If you do not have Extension Manager CC, you can download it from Adobe: //


If you double click an Adobe extension – it will load the default (last installed/used) manager, in your case CS6 – where you wanted CC.

This can happen for CS5 also.

Update: July 18/2015

There is a bug with the latest release of Creative Cloud that prevents users from installing Extensions, here are a few verified solutions by our Tech team to install Export Kit:
