Please verify that you have properly downloaded the release by checking
its digital signature (screenshot attached). If this is not present,
then your install package is corrupted and you should re-download it
using download accelerator which makes sure it is correctly pulled down
from our site.
If this does not help, please provide more info about the error that
you get, so that we can investigate what might be causing it.
Thank you for the patience and understanding.
