What version of NinjaTrader 7 are you using? Please provide the entire version number. This can be found under Help -> About (Example: 7.0.1000.?)

Does this issue persist if you restart your PC?

Do you have any firewall, virus protection, or automated backup software running on your PC? If so, what are their names?

7.0.1000.40
Kaspersy antivirus, same as always. No problems before.

The error indicates that some other program is interfering with NinjaTrader's files. We need to find out what that program is.

Can you reproduce this issue 100% of the time? Or does this appear to be random/intermittent? Does this issue persist if you restart your PC?

Have exceptions for NinjaTrader been added to Kaspersky? If you're unsure, please use Kaspersky's support resources in order to ensure NinjaTrader is ignored by your virus protection/firewall program.
