It should be as simple as the following:

Click the start button

Type Regedit

Right click the Regedit icon presented and choose 'Run as administrator'

In the left hand pane, browse down to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

Create two new keys, which resemble folders in Windows Explorer, called TLS 1.1 and TLS 1.2

In each key, create the following DWORD 32 bit values called:

DisabledByDefault Set the value to 0

Enabled Set the value to 1

Press Windows Button + R and enter IISReset into the Run box and press enter.
