Upgrade Recommendation and Workarounds for Nox Users
Noxturnal Upgrade Wizard
Noxturnal 7.2.0
Noxturnal 7.2.0 has a built-in upgrade wizard for all users upgrading from 5.X or 6.X versions of Noxturnal. This upgrade wizard prompts the user with selections on whether they want to upgrade with their old settings as part of the installation procedure or if they want a fresh installation.
Noxturnal US 7.2.0
Upgrading from Noxturnal US 6.X.X
The Upgrade wizard will pop up with information on whether the user wants to maintain old user settings or if they want a fresh installation.
Upgrading from version 5.x or older
If upgrading in the US market from a version 5.X or older, consider the upgrade instructions here.
Older Noxturnal Versions
If users are working on an older version of Noxturnal (3.X and 4.X), it is recommended to do a fresh install and setup of the software since so many things have changed in recent releases and updating on top will create more problems than it solves.
