Without mention was the need to uninstall a previous version and then reboot prior to installing the latest version of these programs. When it should have been as simple as running a update/upgrade to go to the latest which may not take the first time attempted.
...seems like a scripted program to actually do this would have been in order, one that when ran would uninstall the previous version and then reboot to install a newer version....you know like just about all other software on the market these days.

Been there, done that!
