  3. Power on the VM.
  4. (Optional) Once the jFLR driver is installed and connected, the VM can be powered off again and the Secure boot can be turned on again, without causing the jFLR to lose its connection.

- Or -

  1. The VM can remain in its powered on state.
  2. Download and install the DigiCert Assured ID Root CA from:
    https://www.digicert.com/digicert-root-certificates.htm
  3. Make sure you download the DigiCert Assured ID Root CA with the Thumbprint: 0563B8630D62D75ABBC8AB1E4BDFB5A899B24D43
  4. Open the certificate.
  5. Click Install Certificate.

  3. Restart the VM.
  4. (Optional) Re-enable the certificate validation by opening CMD.exe as an Administrator and entering the following:
