NT7 crashes at start

[babbou]

Hello,

I have just installed NT latest version (7.0.1000.16) on my PC (Windows 7 64 bit).
I could enter license key the first time.
When starting, NT7 crashes immediately (I do not see the control center).

I get the windows error : "Ninjatrader application has stopped working".

I have uninstalled and re-installed several times (after uninstalling, I even removed the Documents\NinjaTrader 7 folder, just to be sure).

I attached the trace file (in Documents\NinjaTrader 7\trace). It shows an error :

2013-10-27 05:02:57:874 Creating CC...

Thank you for your help,

Hello,

Thank you for your post.

I've removed the trace file you included. These files include personal information and should not be posted on public forums.

Please restart the PC to terminate any instance of NinjaTrader running in the background. Next, open the Documents > NinjaTrader 7 > Workspaces folder. Delete the file named '_Workspaces' then attempt to restart NinjaTrader.

Hello Kyle,

Thank you for your answer. I followed your procedure : after restarting the PC, I removed _Workspaces.xml file. NT still crashes at start.
Below the error in the trace file.
