commands with -v

Please always add -v t commands like "gpg --decrypt test.txt.gpg". To decide whether this is smartcard or gpg-agent releated, I need to see a log file form gpg-agent and scdaemon. The latter is more important. I would suggest "debug ipc,app,cardio"

That works using a gpgconf.ctl file side by side to gpgconf{,.exe}

Closing. I don't think we need this "Klammer-Ticket" anymore and it's cluttering my task list.

I'm not working on this anymore. Kleopatra should be prepared for using VSD, GPD, and Gpg4win in parallel (provided they use different homedirs). What's left is the actual parallel installation which might be solved in part by using NSIS for Gpg4win and MSI for VSD/GPD. I'm not sure how the parallel installation of different versions of gnupg is solved, but I guess Werner has that covered.

For KF5-based builds this is resolved because the improved heuristic for detecting light high-contrast themes (like "Desert") is used for VSD 3.3 and Gpg4win 4.4.

For simplicity (and because I think entering tab characters isn't really essential for the notepad) I decided to go with the first solution.

Can't you just use file descriptors everywhere and use _get_osfhandle. That is what I am used to seeing in Windows code in Gnulib (although I do not touch it much).

Regarding 64bit handles https://learn.microsoft.com/en-us/windows/win32/winprog64/interprocess-communication
tells us:

Ready for testing.

This seems to be a good opportunity to replace paperkey with a new tool to take advantage of the smaller ECC keys which allow us to re-generate most stuff.

Ok, it was a missing update (although windows claimed to be up-to-date).
After installing 2025-06 [...] KB5060829 the Microsoft Print to PDF feature is available again and printing also works in Kleopatra/Okular.

A second patch fixes the problem with the button in the smart card view.
