OK I have finally success to test... the master version has a problem with opening pcsc readers on windows I revert back on older version to able to correct this problem. For the current patch without yubikey reference. I suggest validating the interference in the first task for the maybe_switch app function.

Was released with 1.14.0 see T4996

Thanks werner. That helps us to know that such test failure is not a deep issue that would push us to not deliver this version of gnupg on AIX.

For KDF setup (00F9), setting it to '' (null, to reset the DO) doesn't work, but it raises 6a80.
Once KDF is enabled, only factory-reset can reset the feature.

So let's close this task.

Setting the gpg.program configuration value to "C:\\Program Files (x86)\\GnuPG\\bin\\gpg.exe" appears to resolve the issue.

It appears that Git ships with its own GnuPG program set, as can be seen in the attached image. I'll attempt to set the gpg.program setting in Git and see if that helps.

That looks all fine.

With the next release you will get only a warning:

gnupg-2.2/common/t-sexputil.c:467: test 0 failed: Unknown elliptic curve - ignored
This is likely due to a patched version of Libgcrypt with removed support for Brainpool curves

The only download I have executed with regard to gpg4win is from the gpg4win website. You can see the output of the command you specified below.

may give you some clues.

You are not using gpg4win with its included GnuPG 2.2 but some broken gpg version. The error message
"invalid size of lockfile" can only be emitted by the Unix version of GnuPG. Check for other installed gpg versions - there are sites which allows the download of for example a Cygwin version - these version can't work properly on Windows.

I did some test on Windows 10 using gnupg 2.2 with this patch and things work.

For testing ion Windows 10 you need to switch to "Legacy Console" and reboot.

I think that a patch like following is needed:

diff --git a/common/ttyio.c b/common/ttyio.c

Regression with no-unicode font on Windows: T5491

When console font is not a Unicode font, it seems that the WriteConsoleW function returns ERROR_GEN_FAILURE.

Hello Mr. Koch,

The sks pool is now officially gone.

Sorry for the expired certificate.

Fix: "I Know so few about gnupg, thus I'm not sure I COULD add test cases, probably not. "
