NinjaTrader.Vendor.dll access denied error (NT7B6)

[kw123]

Hi,

This is my second time experiencing this problem, the message is in the attached screen shot.

I don't know what I did, basically I just switched from NT7B6 64 bit to NT7B6 32 bit and then to NT6.14, and when I tried to restart NT7B6, I get this error, and I have to a complete re-installation to fix this, can you look into it?

Thanks.

By the looks of is something is holding a lock on NinjaTrader.Vendor.dll.

2 potential sources of trouble are coming to my mind:
- please check in task manager is another instance of NinjaTrader.exe still is running
- some virus scanners unveil a strange behavior by locking the files they are scanning. You could try to exclude the <my documents>/NinjaTrader7 from the scanning list.

I see, thanks Dierk.

kw123, I experienced this error quite a few times when trying to start NT while Visual Studio is running with a reference to some NT dll's. Was Visual Studio running when you ran into the error?
