Cannot open Ninja Trader

[will1abb]

I am trying to download the desktop version of Ninja Trader and I keep getting an error message saying Unable to Connect to DB. I created a support ticket and tried the few things recommended and nothing worked. Would really appreciate some help!!

Hello will1abb,

Thank you very much for your post.

Is it possible your NinjaTrader Desktop application has been installed on a Parallels system?

This error usually occurs if Parallels is set to share the Documents folder between Windows and macOS. This creates a network-shared folder that keeps NinjaTrader from accessing its database, which can only be accessed from a local drive

Please note: Changing the below setting will generally delete NinjaTrader's files, as they are not transferred to the new location. If you would like to retain these files, I would suggest creating a backup first and restoring this after finishing the process.

Mac Installation - Configuring NinjaTrader for Parallels

1. Start Parallels and select your virtual machine
2. Press the "Configure" button on the top
3. Under "Options", select "Sharing"
4. Uncheck "Share Mac" under "Share Mac User Folders with Windows"
5. Press "OK" and start the virtual machine

After changing this setting, please redownload NinjaTrader below and reinstall it:

• You may find the current version in your NinjaTrader Account Dashboard
• After logging in, Click "Download" in the bottom left-hand corner of the sidebar
• Next select "Download" in the "Most Recent Release" Window on the main screen

Should you still encounter any issues after the reinstallation, or would like further instructions (e.g. regarding the backup process), please don't hesitate to let me know!

Thank you very much for your reply. It has not be installed on a Parallels System. I work at an office and had our computer support company look at it and they could not understand why it wasn’t opening either. I have tried uninstalling and reinstalling to no luck. They have tried everything they can think of. They were wondering if there was a telephone number they could call to try to figure it out?
