The version number is in the actual output window.
I see no version number. Screencap attached.
Do you see the output in this same window? If so, does it state the version number as 1.2?
If you do get the window, and you are at v1.2, then it might be CocoaDialog which is missing. To test this, try running: type -p CocoaDialog«ctrl R» in an empty buffer.
CocoaDialog seems to be there.
