I was able to get it working on windows 7 by using some of the changes found on 
the diff file here http://code.google.com/p/volatility/issues/detail?id=92

If you get the error ValueError: IV must be 16 bytes long
Then you just need to provide an IV of NUL bytes.

Here's the one line diff for andrew's patch:

$ diff creddump_updatedfor7/creddump/framework/win32/lsasecrets.py 
creddump_updatedfor7_ivfix/creddump/framework/win32/lsasecrets.py
97c97
<         aes = AES.new(aeskey, AES.MODE_CBC)
---
>         aes = AES.new(aeskey, AES.MODE_CBC, '\x00'*16)

and attached is the combined diff against svn r2 version.

cheers
