Lync SDK 2013 : ForgetMe throws COMEXception

Hi all,

I am currently writing an application using Lync 2013 SDK.

Everything is working fine on my local development machine. Context :

• OS : Windows 8.1
• Lync Client : 15.0.4805.1000
• Lync 2013 SDK installed

Then I tried to deploy my application on a win10 environment :

• I tested various Skype For business clients : 2016 / 2013
• I installed the SDKalways the same behavior when I call ForgetMe :

error: Unable to cast COM object of type 'Microsoft.Office.Uc.SignInConfigurationClass' to interface type 'Microsoft.Office.Uc.ISignInConfiguration2'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{61CE9972-C619-4A88-A5D1-D2DFBCD4D2A1}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

   at Microsoft.Office.Uc.SignInConfigurationClass.ForgetMe(String Uri)
   at Microsoft.Lync.Model.SignInConfiguration.ForgetMe(String uri)
   at Scan.Rtc.Skype4Business.Skype4BusinessClient.SignOut()

When I decompiled the Microsoft.Lync.Model assembly on the forgetMe method :

public void ForgetMe(string uri)
{
	try
	{
		this.m_inn_SignInConfiguration2.ForgetMe(uri);
	}
	catch (COMException rpcException)
	{
		throw LyncClient.HandleException(rpcException);
	}
}

And in the Microsoft.Office.Uc assembly :

namespace Microsoft.Office.Uc
{
	[Guid("61CE9972-C619-4A88-A5D1-D2DFBCD4D2A1"), TypeLibType(TypeLibTypeFlags.FDual | TypeLibTypeFlags.FNonExtensible | TypeLibTypeFlags.FDispatchable)]
	[ComImport]
	public interface ISignInConfiguration2
	{
		[DispId(268435457)]
		[MethodImpl(MethodImplOptions.InternalCall)]
		void ForgetMe([MarshalAs(UnmanagedType.BStr)] [In] string Uri);
	}
}

Maybe someone knows who is responsible to register this COM interface ??

Seems to be inexisting on my deployment machine.

Thank you for your help.

Best,

John.
