If you extract the zip file it will work! Extract everything and then open the knightnurse application.Hope this will help you!
Thanks, but there doesn't seem to be a zip file available only a .rar file. Could you tell me where to download the zip file?
The whole file that you did downloaded is compressed in a zip file. When you download it, drag and drop it on the desktop and you will have the whole file extracted. Then you can open the folder and start the application!
