How can solve NullReferenceException: Object reference not set to an instance of an object ?
I install unity version 5.6.01f3 and import vuforia assest to complete Augmented reality task but when I select ARcamera or any thing the data about this camera isn't appear when inspect this filed like App license key ?! this image can clear more 
I don't know why this data doesn't appear , 
I think it's because of the main problem NullReferenceException: Object reference not set to an instance of an object this all description of the error
NullReferenceException: Object reference not set to an instance of an object Vuforia.VuforiaAbstractConfiguration.CreateInstance () Vuforia.EditorClasses.VuforiaAbstractConfigurationEditor.LoadConfigurationObject () Vuforia.EditorClasses.DatabaseLoadEditor.OnConfigDataChanged () Vuforia.EditorClasses.SceneManager.EditorUpdate () UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/buildslave/unity/build/artifacts/generated/common/editor/EditorApplicationBindings.gen.cs:249)

Can you tell me what is the version of Vuforia SDK you're using?
One possibility for this error would be that, the Unity version (5.6.1f3 in this case) isn't supported with the Vuforia SDK version you're using.
I would suggest updating your Vuforia SDK (if it's not the same) to the latest (v6.2.10 now). You can download it here.
Also I would suggest opening the SDK in an empty project initially since this can happen if any of the script is having a compile error when you're trying to import the SDK into an existing project,
Let me know if you need further help.
Thank's in advance Sir , I use Vuforia SD$$anonymous$$ V 6-2-10 and I can't fix this problem at all .this massage which appear in unity 
Also ,I open SD$$anonymous$$ an empty project without any benefit . The error isn't fixed yet .

Any update on this ? I have the exact same problem, Unity 5.6.0f3 and Vuforia 6.2 (the last one on the Asset Store at this time) Tried with Unity 2017.1 and having the exact same problem. Works fine on Unity 5.5.2 tho.
@Eman_Shaltout did you solve your problem ?
Reimport component Vuforia Behaviour. Reason you remove *.meta or changed some thing on Vuforia Behaviour !
