For those who played this yet there's no sounds, You have to download OpenAL. It's provided with the game once you downloaded it from here. Just head to the "Robbery Bob Man of Steal" folder, then open "_CommonRedist", next "OpenAL", Open the next folder "2.0.7.0", and then open "oalinst.exe" It will ask you for permissions to open the OpenAL installer. Just click yes to proceed. It will open up the installer and show you the license for it. You can read through it before installing it. To install, just click OK and you're good to go. Try opening Robbery Bob and if you hear any music, that means it was successful. I'm sorry if this don't work for others but this is how I got the sounds working for me.
