How do the Proofing tools work in Word 2000?

Does anyone know how the spell checking proofing tool works in Word 2000?
I was familiar wilth the setup for Word 97, where the two files needed for a particular language were given in the Registry.
Local Machine\software\microsoft\shared tools\proofing tools\..1033\
the msspell232.dll and the.lex file.
These files are then located in the
Program files\Common Files\Microsoft Shared\ Proof\.
It seems however with Word 2000, that Msspell3.dll in conjunction with Msspellena.lex and Msspellen.lex, are the important files. Is this the case?
They are in the registry under  
Local Machine\software\microsoft\windows\Current Version\Installer\Components\1360879e82cidiifb5b000a9cf0828a
I dont understand what this huge number/letter bit is. Any ideas?
Pls help!
