Kleopatra comming with Gpg4win 3.1.13 showns "Version Unknown Windows Version" in the about dialog.
Argh, that will also be shown when Kleopatra first starts and no keys are visible. This is caused by a change in Gpg4win to check the integrity of the Version by verifying that the VERSION file is signed.
I've only partially implemented that and forgotten about it before the 3.1.13 release which was not fully planned.
Actually this might be a reason to do a 3.1.14 soon as the next release was planned to have a long beta stage with 4.0
