Cannot connect to database

[e4644]

Hello, opening NinjaTrader tells me it can not connect to the database. I've renamed the NinjaTrader.SDF file but still have the same error. This is my trace file.

Sorry for my bad English.

Hello e4644,

Thank you for your note.

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
• Run the file names SSCERuntime-ENU.exe in which you will want to extract to this directory once more (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 send a note to platformsupport [at] ninjatrader [dot] com and provide me with your phone number so that I may call you to further assist.
