How do I go about upgrading to the latest version of 12?
There is no button with the Check for Updates item like there was in 11...
and I cant find updaing in the prefs when I'm customizing either
The update checker is the same as it was - it hasn't changed from version 11.
By default you can get to it through the Help menu (Check For Program Updates).
You can also just download the new version from our website and install manually.
