Internal error in gpgOL

I have installed gpg4win which includes gpgOL. When I try to encrypt the body of a message using Outlook 2010 I get an error “Internal error in gpgOL. Could not find all objects.” If I try to encrypt an attachment that works. I have tried this on two different WIndows 7 64bit machines and get the same error.

Dear John,
thanks for trying Ggp4win.

Which version did you try?
Is the latest beta better if you haven’t tried it yet?

Best Regards,
