I'm doing some work with GPG encryption and I always like to have a visual/ gui front-end to use to make sure I haven't screwed something up in my command line adventures. I came across Cryptophane today and it seems like a nice way to keep track of my particular Alice and Bob. The only problem I ran across was that my GPG install was in a non-standard place and Cryptophane doesn't look in the registry (I'm pretty sure GPG writes to it). The error wasn't immediately clear and there's no online help (though a .chm is provided), so I thought I'd post this for anyone else who runs into a similar problem. My shortcut target now looks like this:
"G:\Program Files\Cryptophane\Cryptophane.exe" --gpg-path "G:\Program Files\GNU\GnuPG\gpg.exe"

Your paths may vary, etc.
