[Guide] Ripping models from Sketchfab

Hi guys, i tried to use Sketchfab Ripper but it doesn't seem to work on my pc, I use Win 7 x64, disable all my antivirus but the program still won't run (crashes as soon as it runs) I hope you can help me with it and give me a solution, or just tell me some other way to decrypt .binz files, thanks!
