--- Comment #1 from Andre Heinecke <aheine...@intevation.de> --- I think that there are two different Problems here: 1. Claws can't find gnupg (unsupported protocol). This should not happen if you use claws from http://www.claws-mail.org/win32/ afaik gnupg is bundled with this installer. Have you modified your PATH variable not to include gnupg maybe? You can test this by opening a command line (cmd.exe) and then type gpg2 --version. That should show some version information but work. If it does not then you have to add gpg2 to your path again (or reinstall gpg4win) 2. Kleopatra startup in gpg4win-2 was controlled by a small wrapper. If you try to start kleopatra without that wrapper it fails with the dll errors. Use C:\Program Files (x86)\GNU\GnuPG\kleopatra.exe instead of C:\Program Files (x86)\GNU\GnuPG\bin\kleopatra.exe Alternatively you can use the beta of gpg4win-3 from https://wiki.gnupg.org/Gpg4win/Testversions Which has an improved and more stable startup of kleopatra (no more wrapper etc.) -- You are receiving this mail because: You are on the CC list for the bug.
