UWP Build Error

Hey Guys, I'm trying to build my game for the Universal Windows Platform and i'm always getting this error:

 UnauthorizedAccessException: Access to the path "Temp\StagingArea\Data\Managed\sqlite3.dll" is denied.
 System.IO.File.Delete (System.String path) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:179)

 UnityEditor.HostView:OnGUI()

and this one:

 Error building Player: UnauthorizedAccessException: Access to the path "Temp\StagingArea\Data\Managed\sqlite3.dll" is denied.

I already tried to run Unity as administrator but it's not helping. I don't get any errors when building for Android or PC and i'm using the newest version of Unity.

Does anyone know how to fix this ??

Thanks in advantage
