I used the uninstall tool to remove an older version, and then installed the 2.6 framework (tried this twice). When I went to confirm the verion with getInfo it returned "Version: Unversioned, Edition: Premium."
Thank you raising this issue with us. It's something we are aware of, and we shall fix this in a future release. When the fix is available, we shall post on this thread to let you know.
Just to add to my last post - the problem should only present in the simulator. The getInfo method should work as expected on a device.
The problem has now been resolved in Charts 2.6.1
