Viper - 5.0.6.6 and under do as follows.
When Viper ask's to update choose Install
You will be prompted to enter a password, I suggest something simple as all users will use this password to use Viper
Select person from Drop Down and enter the password you just set to Viper
Under Help - Click Maintenance and let it finish.
User Viper as normal
Thanks
I will post any new methods as newer version become available.
