@werner said the reading order should be like on the page https://gnupg.com/vsd/kleopatra-settings.html:

Tested with Gpg4win 5.0.2 (Beta):
Registry settings SOFTWARE\Gpg4win\Kleopatra\<config group>\<config entry>
works (I used [CertificateCreationWizard] EMAIL_placeholder for testing)

This is nothing we want to do in Kleopatra. The "Force" button will be removed shortly even for MDC error.

This has been specified in 1997 by PGP 5 for a good reason. We talked often enough about this and it does not help to repeat your ideas over and over again. RFC9580 specifies a different protocol than OpenPGP as specified by RFC2440 and RFC4880 but alas grabbed the name OpenPGP for this.

b) For non-confirmed keys it returns broken OpenPGP keys (ie. without a user id and thus without important information)

Thank you very much for yours answers, explanations and effort!!!

Yeah sure.

You need to use a current Windows version (and not Windows Server 2016)

keys.openpgp.org has two problems: a) it is a centralized service due to the requirement to confirm mail addresses. b) For non-confirmed keys it returns broken OpenPGP keys (ie. without a user id and thus without important information). For these reasons and the general problems with the keyserver-(networks) there is no more default.

I'm surprised that nobody did detect these problems during the long beta phase...

Please do not use the portable installation - it is dangerous to use it. We will eventually remove this option.

Should work now.

This was fixed in Qt 6.10.0 by adding compatibility code that's "hidden" behind a compiler flag, i.e. we just need to enable this compiler flag. See https://codereview.qt-project.org/c/qt/qtbase/+/629255 for details.

For the time being I "upgraded 5.0.1 to 4.4.1 (in the new directory), and then Kleopatra started again.
When upgrading that installation again to 5.0.1, Kleopatra does not start (same error message as before).

Also: When I click "Abort" ("Abbrechen"), the dialog disappeared, but the main windows does not show any progress: Specifically it does not abort.
I had to press "Abort" ("Abbrechen") in the main window; then the upgrade aborted.
When retrying (and confirming that I don't want to install as Administrator (actually I cannot), the proposed target directory still is "C:\Program Files\Gpg4win".
When locating the previous installation directory (it seems it was a subdirectory of %USERPROFIL%\Downloads) the upgrade succeeded, but Kleopatra fails to start.
It want a bin\Qt6Core.dll, bit in the bin directory there is only a Qt5Corew.dll dated " 14. ‎Juli ‎2023, ‏‎13:23:40".
When retrying the installation/upgrade it announced to upgrade 5.0.1, but then did seemingly nothing (I guess as the version was estimated to "be current").
It seems some "reinstall/repair" option is missing.

We forgot to update the tooltip when the default keyserver was removed in gpg 2.5.3. This has already been fixed in the meantime. Sorry for the inconvenience!

Meanwhile all executables are signed.

The blue Kleopatra icon is now used for the Windows builds of Gpg4win and GPD and for the corresponding AppImages.

Backported for VSD 3.4

Fixed. Kleopatra now looks for programs given as plain name (i.e. without any path) first in the GnuPG installation path (as reported by gpgme) and then next to the kleopatra executable. If the program is found at neither location it is run as-is.

The AppImage now displays the same version as the Windows builds, i.e. in particular Gpg4win-VERSION for the "default" build.

With the recent changes to the build system the current version numbers for the Beta versions of the MSI packages are 4.0.90.<somenumber> for VSD, 5.0.90.xxx for GPD and Gpg4win. Thus we override the standard micro version with 90 to indicate beta versions. Obviously this will require to de-install a MSI beta version before installing the regular version. But we are somewhat constraint by the Windows versioning scheme.

Got reported again with the 5.0.0 release, see

• https://forum.gnupg.org/t/issue-with-automated-installation-of-gpg4win-5-0-1/7098
• https://forum.gnupg.org/t/version-5-automatisierte-installation/7093/8

Is the displayed version 4.0.0.260370 right for the appimage? shouldn't this also display the gpg4win version?

Looks good to me on gpg4win-5.0.1-beta24 @ archllinux:
