NinjaTrader 7 64-bit unable to connect

[kalim]

This morning when I start my NinjaTrader 7 64-bit, it gives me an error (see attached):

Unable to connect to database 'Data Source="C:\Users\Tony\Documents\NinjaTrader7\db\Ni njaTrader.sdf": .....

I don't have this problem yesterday. And I also don't have this problem when I start the 32-bit version.

Could you please help?

Hello sledge,

NinjaTrader requires various Microsoft components to run, one of which is SQL compact Edition. Currently you may not have SQL Compact Edition or possibly have the incorrect version of SQL Compact Edition installed.

Please follow the below steps to ensure the correct version of SQL Compact Edition is installed on your PC. If you are not entirely comfortable performing the steps below, please let me know and we can setup a time for a remote support session.

Navigate to the Windows Control Panel
Add and remove software/programs
Uninstall any SQL Compact Editions you see, if none are present you may ignore this step and continue onto the next step
Install latest SQL Compact Edition 3.5. SP2 which is available here: Download Here
Once you run the downloaded file it will ask you for a directory to extract the installer to. Point this to a temporary directory that you will be able to quickly locate later, such as the desktop
Navigate to the aforementioned directory in which the files have been extracted to (there will be two files)
SSCERuntime_x86-ENU.msi - Run this one first
SSCERuntime_x64-ENU.msi - No need to run this if you are on a 32 bit system, if you are on a 64 bit system you will also need to run this file, if you are not sure if you have a 64 bit system go ahead and run this file. If you are not using a 64 Bit operating system, the installer will cancel itself automatically
Follow the installation steps outlined in the installation wizard
Once installed you will need to restart your PC
You will now be able to launch NinjaTrader 7
If you are unable to launch NinjaTrader 7, please let me know so I further assist.
