unable to generate computer id for Mujoco licence

Hi,
I have Tx2 with ubuntu 18 which I use for my research purpose. I would have to use mujoko physics engine.

To activate its license computer id has to be generated as mentioned in its website.
https://www.roboti.us/license.html

I get the following error on running it and doesnot crate computer id. This blocks from procuring mujoco license.

cstx2@cstx2:~/Downloads$ ./getid_linux
bash: ./getid_linux: cannot execute binary file: Exec format error

Has anyone tried this? any work arounds?

Thanks
