Firmware Update to a Sony DW-D22A

I have a Sony DW-D22A and understand this is the same as the DRU-710A and I should use BSOY firmware

-I have downloaded “BSOY.EXE” from
-I have the progarm LtnFW from
-I can back my current firmware up using this program.

What I am unsure of is how to update the firmware of my Sony DW-D22A. My understanding is that I run LtnFW, select a binary file from a folder and then select “update” and hit start. I do not know how to get this binary file and the file I downloaded “BSOY.EXE” but it is an executable. Do I just run this executable and I don’t need to use “LtnFW”?

Can you please provide me with some guidance?

Probably this thread should go into the LiteOn/Sony subforum?!
