I accidentally sent the previous reply directly to René, so included below.

I created the registry entries and rebooted per other instructions from 
Google search:

C:\Windows\System32>reg query 
HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols 
/s
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 
1.0
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 
1.0\Client
     Enabled    REG_DWORD    0x1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 
1.0\Server
     Enabled    REG_DWORD    0x1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 
1.1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 
1.1\Client
     Enabled    REG_DWORD    0x1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 
1.1\Server
     Enabled    REG_DWORD    0x1

No joy:
