Unable to install latest version of NT

[gapsmeister]

I tried upgrading to the latest build of NT but it will not install.

When i try to install 8.1.1.3 the install rolls back and setup does not finish.

Interestingly I tried uninstalling from Windows to do a fresh install, Windows also rolls back the uninstall??? So NT won't uninstall from Windows.

The update also corrupted the current NT install. Now NT won't open at all.

I'm running Windows-11 64 and NinjaTrader-64 8.0.25.0

Hello gapsmeister,

When the installer rolls back that usually means some file in the user data directory or the program files directory is open. Restarting the PC usually helps.

A common reason for this is leaving visual studio open with the NinjaTrader project loaded, that will prevent both an install and uninstall.
