I downloaded derive6-demo-english from the site that you provided, installed it
on windows XP, downloaded derive6-update6_10-english, and when I ran this
update program I got the error

The file c:\deriveUpdate\Derive 6 Trial Edition\Derive6.exe is not a valid
previous version and could not be upgraded.

Note that on Linux under wine I am running the 30 day trial version of Derive
