Tried re-downloading and installing. Nothing happens. File size was only 872 kb. I then deleted the file and re-downloaded. Tried several times kept coming up as zero bytes. After 5 tries I got the full download (I think) 15,298 KB. However it will not install either. Hour glass comes on for a second or so then goes away. Nothing else happens.
