beta 7 db error msg

[ATI user]

every time I add a strat to a chart or enable/disable it I get the attached db error...i.e. constantly

[NinjaTrader_Dierk]

Is this a strategy from an imported NinjaScript assembly? Or can you reproduce the issue with SampleMACrossOver?

[ATI user]

it happens with SampleMACrossOver..constantly

on adding to chart
on enabling
on disabling

have seen it 60+ times during test strat persist issue with only SampleMACrossOver

Please try this:
- uninstall NT7
- manually remove the installation folder <program files>/NinjaTrader7
- reinstall NT7

Thanks

Edit: All your data, settings etc. will be maintained by performing steps above.

I’m getting the same error each time when I sent order either from DOM or chart. I don’t have active any strategy.
It start happening right after update to Beta 7.
Please advice
“Failed to execute DB job 'StrategyUpdateJob': Could not load file or assembly 'System.Data.SqlServerCe, Version=3.5.1.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

Guys,

Thanks for reporting that issue. There now are a couple of reports on the forum on the exact same issue. I'll try to funnel those through that thread. We had been unable to reproduce the problems you experienced at that time but we are suspicious about one issue:

Do you have any NinjaScript assembly loaded? Please check in File->Utilities->Remove NinjaScript assembly.

If so, then please remove any of those assemblies and restart NT to see if that makes a difference.

I'll provide further info in a follow up.

Thanks

Edit1: As it stands my post #4 below is the way to go and NOT this post. Anyway, I'll leave it up since I used it as reference.

Edit2: NT7 comes with modified SQL CE assemblies to avoid conflicts which some users reported as they had e.g. VisualStudio installed: NT7 now uses "it's own" version of the SQL CE assemblies. There appears to be a problem with the Microsoft installer which would not clear out the folder <program files>/NinjaTrader7 on updating NTB6 to NT7B7. This could be resolved by steps provided in post #4.

Please try this:
- uninstall NT7
- manually remove the installation folder <program files>/NinjaTrader7
- reinstall NT7

I had received the error message when connecting to ZenFire...but these steps fixed the problem for me. No errors now when I connect to ZenFire.

that solved issue Dierk....

I had trouble deleting Program Folder/NinjaTrader 7/bin folder. Windows thought it was open. I restarted computer which allowed me to delete.

I do not have any imported assemblies in Remove Assembly

Great, thanks for your feedback. As stands my post #4 and not my post #6 is the way to go.

Just FYI... this solved the problem for me as well.
Was getting same error when trying to do a Database reset.

I had installed on top of Beta6... doing an uninstall then re-install of Beta 7 fixed the problem.
