When importing the Virtual Appliance OVA into vSphere, you may see a warning “OVA certificate not trusted”. If this is the case, please follow the steps as listed in this VMware KB.
You may find even after this step that the OVA certificate is flagged as “Invalid Certificate”. If this is the case we recommend downloading the certificate (as displayed in the web interface) and manually verifying the Cristie Software digital signature before deployment of the OVA in your environment,
