Terminal does not understand a space in a folder or file name, it thinks your ending the command and adding another argument. if you want to CD into Rockwell Software directory, you either need to use quotes, or use an escape (backslash) before the space so it knows you really mean a space in the name. cd Rockwell\ Software or cd "Rockwell Software" then keep cd down in there until you get to the folder that has the actual exe file in it to run with Wine.
