winhttp.dll on windows 2008 r2 x64

hello,

I use WinHttp.WinHttpRequest.5.1 object and the PCI DSS provider upgrade to TLS 1.1 and TLS 1.2

if I try to use any of this options:

obj.Option(9) = 2048  'TLS 1.2

obj.Option(9) = 512 'TLS 1.1

I get an error.

I upgrade all the kb realted but I get the same result

if I try from web-browser the URL load using TLS 1.1 and TLS 1.2

what is the solution ?
