Hi,

It looks like GPG4Win as well as "simple" installer are 32bit-only,
which is somewhat unexpected in 2022. Is there a reason for this?

Such builds are unusable with the x64 Thunderbird [1], no matter if user
has enabled `mail.openpgp.allow_external_gnupg` preference, replaced
`rnp.dll` with one from Sequoia project [2] or both.

There are reports [3] of using x64 build with success, however I don't 
immediately see anything recent, the latest v2.3.7 is published as 32b:
