Can't connect to NT

[pandyav]

For some reason this morning I got disconnected from NT and when i try to open the program this is the error message:

Unable to connect to database 'Data Source = "C:\Users\Trader\Documents\NinjaTrader7\db\NinjaTr ader.sdf"': ObjectSpace: connection String is Invalid - Exception has been thrown by the the target of an invocation.

Can someone help with this please?

Thanks

I have the same issue.

I downloaded and installed NT7 for the first time and I get the same error message, and NT crashes

I will continue to search the forum for a solution, thanks.

X-RAY,

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 email us at support[at]ninjatrader[dot]com and provide us with your phone number so that we may call you to further assist.
