W10 Yubikey cannot open pinentry
In the wiki on how to use an external GPG provider it says to use GPG4Win's bin_64 directory but this is no longer correct. The problem then is that Thunderbird doesn't know how to raise pinentry.
Today, with W10, Thunderbird 102 and GPG4Win 4.0.2 you cannot use a smartcard like a Yubikey by following the wiki: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards#Thunderbird_64_bit_on_Windows

Sorry, there *is* a bin_64 directory. The problem has been ported to the thunderbird.topicbox.com as it's not an issue with the wiki.
