The lame_enc.dll file in this ZIP is version 3.99.5 compiled in 32bits.
It is known to work with Audacity 2.x

If you come across any problems, please use the recommended 3.99.3 version
from http://lame.buanzo.org

To install, just extract lame_enc.dll to a well known folder, and when
exporting as MP3, Audacity will ask for that file. Point it to the well
known folder.
