Yeah, it worked fine when I tried it this time.
Which version and where did you download it from?
I realized I gave you a link to the site which has only the zip file. I think that's the one that didn't work for me before also. I believe that's the source file.
Try this one http://github.com/clivecrous/vultures/downloads
assuming you're running windows, get the third one down from the top,vultures-2.1.2-eye_win32-1.exe
Run that and it will install to wherever you tell it, it should also make a desktop icon. From there it should work perfectly, sorry about the mixup.
