Problem running Ninjatrader x64 version

[mbesha]

Hi. I have been using Ninjatrader, both the 32 and 64 bit versions, for a while now with no problems but recently I seem unable to use my 64 bit version. Every time I try to click on its icon and run it I get the message "Unable to connect to database 'DataSource= "C:\Users\jim\Documents\NinjaTrader7\db\NinjaTrade r.sdf"' : ObjectSpace: Connection String is Invalid". On the other hand, the 32 bit version runs without any problem. Could you please advise me on how to correct this problem. Thanks.

Hello mbesha,

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.

Thanks a lot for the advice. I followed your instructions and now the 64-bit program is up and running.

On my Windows 8 machine (with this same issue), there is only one .msi installed, and it does not make reference to the 32/64 bit-ness issue.

There is no information regarding "where to install" this thing.

Running the installer does seem to make NT64 load and run without the error.

I have not yet rebooted the machine.
