Public keys imported but still shows no public key when encrypting

Gpg4win help-en

Hi everyone,
The software of our company use two public keys to encrypt our files. One key comes from my company and the other comes from Livermore Software Technology Corporation.
Today I installed GPG4win on our user’s computer and tried to encrypt file in CMD, but it showed “no public key”, although I could see them with “gpg --list-keys Key-ID” command and in Kleopatra (picture below).

The version of the installed GPG4win is 3.1.2, and it didn’t have any problem on other users’ computers.
Does anyone know what could be the problem?

Dear @yuyunlu

use --verbose to see more, or maybe even --verbose --verbose.

As the keypairs are quite old, it maybe the case that they use an algorithm that is not considered secure anymore (like md5). There are a couple options where you can force to use some of the elder algorithms.
