NinjaTrader 64 bit wont start after Windows 7 update

[djwhite81]

I have Windows 7 64 bit and yesterday it applied new updates and today when I went to use NinjaTrader 64 it gives an error trying to open NinjaTrader.sdf. I deleted the file and tried again, but it did the same thing even though it created a new file. I opened the NinjaTrader.sdf with NinjaTrader 32 bit and have been using it since then. Any ideas on what caused this?
Thanks.

Hello djwhite81,

Welcome to the NinjaTrader Support Forums!

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

Let us know if the issue persists.

That seems to have taken care of the problem. However, I do have SQL Server Compact 4.0 SP1 x64 before this started happening. So it appears NInjaTrader 64 is not compatible with SQL Server Compact 4.0 SP1 x64. It's possible the update removed SQL Server Compact 3.5 SP2. But now I have both of them and it does work using the 64 bit NinjaTrader. I think I found the reason why the 32 bit NinjaTrader would work when the 64 bit would not after the Microsoft updates - I also have a SQL Server 2005 Compact installed. Anyways thanks again.
