About TLS Support

You must install the following software packages to support transport layer security (TLS) 1.2:
  • Microsoft .NET Framework 4.7
  • Microsoft SQL Server Native Client for the SQL Server (the minimum required version is 11.4.7001.0)
Consider the following points to enable TLS 1.2 in operating systems:
  • TLS 1.2 is already enabled in Windows 8 (and later versions) and Windows Server 2012 (and later versions) operating systems. To use TLS 1.2 in these operating systems, you must add registry keys to disable TLS 1.0 and 1.1.
  • To enable TLS 1.2 in operating systems prior to Windows 8 or Windows Server 2012, you must add keys, and modify existing keys to disable TLS 1.0 and 1.1.
Note: Use the following URL to access the keys: https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn786418(v=ws.11)#BKMK_SchannelTR_TLS10.
