[Dx4win] Upgrade - Newbie Question

[Hal Kennedy]

Just starting out on DX4WIN and into my first problem.   Sorry to be
asking "easy" questions.
 
I installed 8.03 and have it running fine.
 
If I download 8.04 and install it, it installs in C:\dx4win804, a
completely new entity including all the subdirectories, and has no
access to my license.  I'm sure I could move my license there from the
install that's still at C:\dx4win803, but what about all the saved
files, etc?.  Anyway, I uninstalled 8.04 and reading what I thought were
the directions more carefully, I reinstalled it into C:\dx4win803.  It
winds up creating an entire new entry with all the subdirectories in
C:\dx4win803\dx4win804.  
 
I give - how do you really do this?
 
Thanks,
