Right click on the OutsideVoice_Linux folder underneath OutsideVoice_Linux.zip on the left sidebar, and then select copy! Then just go to My Files->Linux Files and paste it into there! I think ChromeOS only treats the files inside that directory as linux files.

Ok, ignore that page for now its basically the same instructions but for a different game (provided as a reference). Were you able to successfully copy the files to the linux files folder, and are you able to open the terminal program?
If you are unable to right click, you can also try pushing the ALT key while left clicking.
.....oh, shoot... can you tell me what your chromebook model is? I have a suspicion what might be happening, but I’m hoping its not the case...
1) It’s “L S” not “1 S”, but that command shouldn’t matter
2) Can you also try chmod +x OutsideVoice.x86_64 and then ./OutsideVoice.x86_64, and see if it works?
