No internet connection required and as long as you extracted the folder and kept all the files together it doesn't matter where you launch it from. Try holding shift and double click the .exe to get launch settings and see if that helps. Otherwise I don't have any diagnostic tools built into the app so I can't do much to troubleshoot remotely. I'm sorry it's not working for you. Please let me know if you figure out what's going on.
