using a smart card/YubiKey 4

I havea YubiKey4 with my keys properly loaded into it. I'm trying to use it with THunderbird/enigmail for PGP encryption. In enigmail I see the "manage Smart Card" option, and I can see and revise information in that window, but I can't get Thunderbird to recognize the Yubi Key as the location to look for my private key. I saw some discussion in other forums about pksc11 and setting the certificate to trust, but when I look for that package to load it, I'm not seeing anything on my computer. Is there a plug in I'm missing or another setting that I'm not doing correctly? Happy to provide more information if you need it, but this issue has come up on both of the windows 10 PCs I tried it on. Thanks

Perhaps the enigmail add-on? https://addons.mozilla.org/en-US/thunderbird/addon/enigmail/?src=hp-dl-featured

No, enigmail is there, as I noted in my post. I found dead some references to placing the key stub somewhere, and I'm thinking that's what's going on. I created the key on a different computer from the other essential I'm using for Thunderbird/enigmail. Wondering if the stub FIL is somewhere on the computer I used to generate the keys and if that's the issue. Not sure where to find that, though.

Enigmail is based on GnuPG (www.gnupg.org) for the cryptographic functions.

Note: GnuPG is not part of the installation, but will be downloaded as part of the setup process.

Have you installed gpg4win? https://gpg4win.org/
