Two factor authentication enabled

[JGRtrader]

I am not able to get 8.1 to run and have to uninstall it and reinstall 8.0 to have the desktop application.
I have created the new live account. I use the old credentials for the 8.0 desktop version.

I get this message when I try to start 8.1. The message says it will send an email to rectify the problem but no email arrives. I do not have two factor enabled for NT.


The history is that when I first tried installing 8.1 my computer crashed hard requiring a power off reboot. Since then I get this message when I try to upgrade.
Now I have a new account but run the old 8.0 desktop. I received some complex instructions on April 11 from Support about how to install on an new computer. This is not a new computer and it requires using the building backup which does not carry the Visual Studio "sln" file which I must have.

Today, I tried again with the latest R8-1-1-6 hoping that maybe it would work. No Luck. I am looking for way to get the desktop application update installed without reformatting C: drive and reinstalling Windows 10. BTW, My machine runs Intel 7th generation which does not support Windows 11.

Please advise.​

Hello JGRTrader,

Thank you for your post and for your patience.

The email for two-factor authentication should come from support[AT]ninjatrader[DOT]com. Please check your spam/junk folders for this message. The subject line would be "Login from a new device." Otherwise, another option would be to log in to the account dashboard and disable two-factor authentication then try to log in to the platform again. For more details on enabling/disabling two-factor authentication, please see the help article here:

Although your PC does not support Windows 11 that is not an issue; Windows 10 is supported per the minimum PC requirements listed on the installation guide here:

Please let me know if I may be of further assistance.
