Preferences->Android SDK Location error

Now I am going but I get an error that I want to do with the development of Android Unity3D.

The error is

SecurityException: A security error has been detected. Microsoft.Win32.Win32RegistryApi.GenerateException (Int32 errorCode) Microsoft.Win32.Win32RegistryApi.OpenSubKey (Microsoft.Win32.RegistryKey rkey, System.String keyName, Boolean writable) Microsoft.Win32.RegistryKey.OpenSubKey (System.String name, Boolean writable) (wrapper remoting-invoke-with-check) Microsoft.Win32.RegistryKey: OpenSubKey (string, bool) Microsoft.Win32.Registry.ToKey (System.String keyName, Boolean setting) Microsoft.Win32.Registry.GetValue (System.String keyName, System.String valueName, System.Object defaultValue) UnityEditor.AndroidSdkRoot.GuessPerPlatform () (at C: / BuildAgent/work/842f9557127e852/Editor/Mono/Utils/AndroidSdkRoot.cs: 13)

This error preferences-> occurs when you click on the column designated Android SDK Location.

Determined because no path for this error can not be built.

We're completely stuck on this.
