You can install the earlier version.
Scroll down to lower part of the creative cloud desktop app window, and choose "earlier versions" instead of "all"
(all is selected by default and it doesn't show earlier versions if selected)
You can now choose DW CC (version 13), and install it.
2014.1 is supposed to be miner update of 2014.0, so you can not install both in the same computer.
I decided to stick to ecart 5 with DW CS6 and use 2014.1 as well.
Hoping soon I can use ecart 6 and other new extension with the 2014.1.
