How to enable TLS 1.2 protocol on Windows

To ensure the proper connection of the Qualibrate, the TLS 1.2 protocol has to be enabled in Windows. This can be done by a user with permission to use the registry.

Procedure

The following procedure can be used to check and enable the TLS 1.2 protocol:

1. Launch the Run accessory with its Windows key + R keyboard shortcut

2. Input ‘regedit’ in Run, which will open the Registry Editor.

3. Then open this registry key path in the Registry Editor:

   • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

4. If users can’t see TLS 1.2 and Client subkeys, they’ll need to create them. Right-click Protocols, select New > Key, and then enter ‘TLS 1.2’ as the key title.

5. Next, right-click TLS 1.2, select the New & Key options, and enter ‘Client’ as the title for the second subkey.

7. Enter ‘Enabled’ as the new DWORD’s title.

8. The default value for the Enabled DWORD is 0, which disables TLS 1.2. You can double-click Enabled to edit its value with 1 (TLS 1.2 on).

9. Close the Registry Editor and restart Windows.
