I was able to get this working by:

1. Closing my project (File -> Close Project)
2. Open SDK Manager from the gear at the bottom of the window
3. Click Updates on the left
4. I had to do this twice and it worked the second time.

If that won't work you can try File -> Invalidate Cache/restart -> Invalidate Restart. Android Studio will close and restart and then updates should install properly.

After delete, you reinstall here "Instant"
