It's not all that different. C:\Documents and Settings\<username> is now
C:\User\<username>. "Application Data" is now AppData. The change is the
addition at the next level of several directories to group data: Local,
LocalLow, Roaming.

GnuPG's application directory will be in Roaming.  Running "gpg --version" at a
command line prompt should confirm that. SSHing to a Vista box, I got:

Locate GnuPG's HOME directory. The default on Vista (and I believe Windows 7)
will be C:\Users\<username>\AppData\Roaming\gnupg\. Running gpg.exe with the
--version switch will confirm this - just look for the line starting Home:.

Copy/move idea.dll to there.

You can safely delete that addition. I don't think anything uses that registry
value any longer.

In the same directory to where you copied idea.dll, use Notepad to create a text
file named gpg.conf. Include the line

    load-extension .\idea.dll

You may include other options in gpg.conf as well, but that line is what you're
looking for. Running "gpg --version" again should show IDEA as an available
cipher algorithm.

Feel free to ask any Enigmail questions on the Enigmail list, enigmail at mozdev.org.

Good luck.
