When I use the .tie file from the Steam Crossover page, it gives me the error message "Empty crosstie. The crosstie you chose contains no applications, so there is nothing for us to do."
I tried downloading and installing the steam.exe file from Steam and that doesn't work either. I get the error "Sorry, Steam is not supported on Chrome OS."
What am I doing wrong? The steam page explicitly says it should work for chrome os.
