Today I set up a GPG installation on a Windows 7 machine and I ran in to a problem. My problem was that Thunderbirds extension Enigmail, didn’t recognize the Cryptophane frontend. Cryptophane is a Windows frontend which makes the handling of keys, en- and decryption of files very easy for everybody. When I tried to make mail encryption work in Thunderbird, I got the following error message:
Unable to locate GnuPG executable in the PATH. Make sure you have set the GnuPG executable path correctly in the OpenPGPG Preferences. Failed to initialise Enigmail. Send unencrypted message?
How to fix?
First I thought, I had to use another GPG frontend which would work with Enigmail, but in the preferences of Enigmail, there was a lot easier solution.
- open Thunderbird
- open OpenPGP -> Preferences
- mark “override with”
- click “Browse” and find your Cryptophane installation directory (for example: C:\Program Files\Cryptophane\GnuPG\gpg.exe)
