GnuPG for Win (XP) Installation

[Sean C. C.]

I downloaded the gnupg for windows freeware. But am a little confused 
about the installation process. I have PGP installed also, but plan on 
uninstalling it. I don't know if that affects GPG and its installation 
at all.
Anyways, I downloaded the zip and sig. The sig I ended up doing nothing 
with. I extracted the zip and according to the readme.w32 file copied 
the exe's to directory c:\gnupg. I also double-clicked on the .reg file 
to add those keys to my registry. I'm not sure what else I need to do. 
When I try to use the enigmail plugin for Thunderbird 1.0 it tells me 
that gpg can't find 'iconv.dll'. It was not included in the .zip file 
and the readme.w32 does not mention it at all.

In fact, the doesn't explicitly say to move any files to the C:\gnupg 
directory only to create it (or another directory of my choosing) and 
create the registry keys. Since I followed the instructions I'm 
*assuming* that the included registry keys should work. For what I'm not 
sure. Then to enter gpg and see what happens. Well, it would appear that 
when I did that from "my documents" it created public and secret 
keyrings in the c:\gnupg folder.

Below is what happens when I try to create a key:

C:\>cd gnupg

C:\gnupg>gpg --gen-key
gpg: error loading `iconv.dll': The specified module could not be found.
