The file size & sha1sum given for Gpg4win 2.0.2 RC2 at http://www.gpg4win.org/download.html don’t agree. File size is actually 72,040,335 bytes (huge difference from listed 35 MB). The sha1sum I get for this file is fb8c9707e69ce944ef46a2d5d61f9f7e45df7a57, also different from that listed at above site.
I assume this error is because the release is so new. I’d rather wait for confirmation of correct verification info before installing.
