My previous *Archive and Install* as has been noted leaves a number of files in the old System folder that you then have to sort through in order for things to work. This is why Macromedia Studio 8 and a few other things didn't work.
I don't have time for this. So instead, I just did an
Upgrade install. So far everything now works well and as expected.
Except for printing, which is totally hosed. That's another thread.
