Since the support for 4.6.11 is over, I just performed a fresh install of K2 SmarForms 4.7.
However the main page of Designer does not show the version like used to be 4.6.11 now is just empty.
I wonder How To idenfity the SmartForms version from the Main Designer in 4.7 
Although this may be a less direct methods, if you have access to the K2 Server; looking at the K2 components in "Programs and Features" will indicate version number 4.16060.2000.x. This will indicate version 4.7.
