I can't run NinjaTrader 8

[alexstox]

Hi, NT8 worked fine previously on my laptop with Windows 10. I tried to run it today but it failed.

I downloaded the newest NT8 version and installed. But nothing happens, when I try to start the app even as administrator, without any process in Task Manager.

NT8 added in the whitelist to Windows Defender Firewall.

What should I do?

Hello,
Thanks in advance; I look forward to resolving this item.

I did, I sent you screen-shots and a short video of the running and installation processes.

To resolve this please uninstall and reinstall NinjaTrader. Following these steps will not affect your data, settings, configuration, NinjaScripts, Workspaces, etc.

• Exit NinjaTrader and uninstall NinjaTrader within Windows Control Center
• Once uninstalled you can re-download NinjaTrader
• Download and then run the installer

This worked for me. Special thanks to Dennis.

I'm having the same problem. Windows 10 pro. I've installed the application. When I try to open either the 64bit or 32bit, I get the spinning icon, then nothing. There is no foldler in the documents directory called Ninjatrader, so I can't send anything to you. I've uninstalled and reinstalled, and rebooted. No joy!

[alexstox]

craigsn, if you installed the app successfully, you might have Ninjatrader folder in Documents - you can find Documents at the left-hand side, when run File Explorer or open any folder. Because by default your personal settings, workspaces etc. are saved in Documents/Ninjatrader

For these types of errors, it is always best if you contact us via email - there is not enough information to go on in the forums to provide you with any meaningful support for what you're experiencing. You can use the email address I provided in my earlier post and just be descriptive about the symptoms. We'll get your NinjaTrader up and running.

Ok. I'll do that Patrick. Thanks for the prompt response

popil2203 , so I may accurately assist you, please answer all of the following questions:

• Was NinjaTrader working before? Or has it never worked?
• Do you receive an error on screen? If so, what do these errors report?
