Registry disclaimer
Important
: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

  1. **Backup the registry** How to back up restore registry in Windows.
  2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
  3. Look for any folders in \Protocols labeled TLS 1.0, TLS 1.1, SSL 1.0, and SSL 1.1.
  4. Under each folder, there should be 2 subfolders labeled Server and Client.
  5. In each \Server and \Client folder there should be a registry labeled Enable, double click and change the value data 0 to 1.
    • If there is a registry labeled DisableByDefault in any folder, make sure their values are set to 0.
  6. Restart computer and reload Venus 1500.

NOTE: We have seen issues resolved by enabling all TSL/SSL 1.0, 1.1, 2.0 and 3.0 Client and Server registries at the same time.

We have also seen instances those folders do not contain a client folder. If this is the case continue by following the process for the Server registry.

If possible, try to isolate to an individual registry value.
