I did 2) above and it worked "out of the box."  I copied it to Kevin
rather than root, others may want to do that instead.  I copied it to
it's own directory (Office52) and it created it's own directory
(office52) and I ran it from there.  Now, if I delete SO 5.1, will that
affect 5.2 in my home directory?

At first glance, I like 5.2 much better.  Give me some time and I might
find something which I won't.

Thanks Grant for the help.
