LiteOn XS0Z binary firmware needed

I want to update/cross-flash some Sony CRX-185E1 drives to the latest LiteOn LTR-32123S firmware, XS0Z, but can only find the necessary file (on LiteOn’s website) in a compressed .EXE format.

When I run it, the software (of course) reports the drive as a Sony and won’t update the firmware.

Most of the links to firmware sources are dead, or do not have what I need.

Does anyone have this firmware in BINARY format?
