Hi BarcloudUser
Within the above Blog John_W has said:-
"...If you're using Windows 10 and download the installer from the MYOB website, you might get a Setup failed message when installing. In this case, you’ll need to uninstall 2015.3 before installing this update...."
I suggest that in your situation you should uninstall 2015.3 before installing the update.
The update worked in my case because I had Windows 10 Pro 64bit installed; you may be using the 32bit version of Windows 10.
