How to download ans install DSDplayer for transporter?

Hi I have a transporter, but have not used for many years. And I don't know about LMS too much. Just beginner level, in learning.

One question, how could I download and install DSDplayer for my transporter?

And DSDplayer only allow transporter to output DSD digital singal, right? And I have to connect transporter to a DSD capable DAC through SPDIF cable, correct?

Pls advise, thanks!
