Can't intall Photoshop CS6 - "Inconsistency in Installer Database"

Question

This is terrible.  Was using GIMP; found CS6 on sale, thought I'd give it a try.  I'm missing GIMP already.
Bought fresh new DVD.
Ran installer.
Fails.  Here's teh dump:
"Your installation encountered errors...Inconsistency on the installer database.  Please restart..."
Exit code:15
ERROR: ASU has quit unexpectedly.
ERROR: Media DB Error : 18
This is like DOS-era stone age error message and failure recovery.
Restarted.
Still fails.
Went to adobe, manually registered my serial number; website accepts it.  Re-tried installer, still fails.
Ran the diagnosis utility; no dice.  The Token is 40-69367-113227092012.
Wasted time trying 'cleaner' - no dice.
WTF!?!
