Unhandled Exceptions error

[Bamzor]

I have been battling this error for 2-3 months. Tried using previous forum responses/suggestions. Currently Ninja is updated to the most current, uninstalled using a cleaner/Reuploaded. I have 2 addons that I added 10 months ago that work flawlessly. I am trying to add a Newsguard Indicator, but get the attached message, then Ninja shuts down. I do not have Dropbox on my computer as it has caused a similar error for others.

Hello Bamzor,

Thank you for reaching out.

This type of error message indicates that something is blocking NinjaTrader from accessing its own files.

A first step to try, would be to restart your PC, as to end any active process that may be using your NT8 files, then re-launch NT8.

Usually this has to do with any back up software (exOneDrive) or the directory where NT8 files are.

If after restarting your PC you still get that error message I have outlined a few different troubleshooting steps below to combat this error.

Windows Firewall/Anti-Virus

First, please check for any virus protection, firewall, and backup software you may be running, and add exceptions for NinjaTrader so that they do not interfere with NinjaTrader's operation.


Disable Controlled Folder Access

Next, press the "Windows Key" on your keyboard > Search for "Controlled Folder Access" > Click on "Controlled Folder Access" > Turn "Controlled Folder Access" off if it is enabled

• This can be restricted by administrator settings. If you are unable to access this setting, please contact your network/PC administrator.
• Additional information on Controlled Folder Access may be read at this publicly-available link from Microsoft's website: https://support.microsoft.com/en-us/...ndows-security

"Hidden" and "Read-only" Folder Settings

Next, try to adjust the read/write protection for NinjaTrader 8's documents folder:

• Go to your Computer\Documents folder > right-click on the NinjaTrader 8 folder > select "Properties".
• From the Folder properties, ensure that the Attributes have both "Read-only" and "Hidden" unchecked.
• When prompted to Confirm Attribute Changes, please make sure to select "apply changes to this folder, subfolders, and files" and press OK.
• Re-open the platform to see if the error persists

Uninstall/Reinstall NinjaTrader 8

Please follow the steps listed below to complete a quick uninstall and reinstall NinjaTrader. These directions will keep you from losing any of your information.

• Close all running applications.
• Do not do anything to the Documents/NinjaTrader folder
• Uninstall NinjaTrader within Windows Control Panel.
• Navigate to "C:\ > Program Files (x86)" > or "C:\ > Program Files" Delete the 'NinjaTrader 8' folder if it exists
• Reboot your PC.
• Once these steps are completed, download and install NT8 using the steps below:
  • Login into the NinjaTrader Account Dashboard
  • Click "Download" in the bottom left-hand corner of the sidebar
  • Next select "Download" in the "Most Recent Release" Window in the main screen
  • Once the installation had downloaded, ensure any previous version of NinjaTrader is closed before running the installation package

Before restarting NinjaTrader, be sure all available updates are installed to your PC from the Windows Settings > Update and Security page.

Be sure to manually check for updates here, and reboot after any updates are installed.

Please let me know if these solutions work for you, and feel free to ask any questions you may have as you work.
