NinjaTrader database access error solved - Repair MDAC Type on Windows XP SP3

I just installed the NinjaTrader Version 6.5.1000.14, when launching the Ninjatrader, it pop up a message box showing the error accessing the accesss database due to the MS JET version is not 6.0.

But when i try to run the MDAC Type 2.6 and 2.7 installation, it ran through smoothly but doesn't solve the issue.

If i to run the windowsxp-kb829558-x86-enu.exe downloaded from http://support.microsoft.com/kb/239114/, it gives me a message box saying that i've JET even newer and not necessary to update.


I checked my msjet40.dll the version is 4.0.9511.0 Windows XP SP3 and Security Bulletin MS08-028. When i run microsoft component checker, it said i use mdac 2.8 SP1 on WinXP SP3. (see attached image)


I also have tried to uninstalled Ninjatrader and install with Version 6.5.1000.13, but facing the same problem.

I'm using the .NET Framework 3.5 on Win XP Home.

After continue research, the solution below solved the problem, it's due to the MDAC file corrupted, nothing concern with Ninjatrader. As Ninjatrader need to access to Access database using the MDAC :

My Venture Begins

I've seen so many bloggers on the web, and i think i should start something my own - to share with you my venture in the Foreign Exchange Market (FOREX) trading world.

My venture centric on my preference in algorithmic trading, and all my experience in the product and live experience on each of them. And I also will go in-depth to automate my trading with the Expert Advisor (EA).

The way to pave the road to find solution in FOREX market trading to me will never stop. My approach to successful investment in this market would be :-

i)Find one or few strategy for manual trading and continuously improve it.
ii)Let someone who has the expertise but don't intend to disclose it to manage my account.
iii)Create EA to trade my account automatically.

I will distribute my fund to each of the above approach and i believe this is a building path to financial freedom for myself and anyone who want to join me.
