This documentation outlines how to install and register vTDM: https://docops.ca.com/ca-test-data-manager/4-3/en/virtual-test-data-management-vtdm/install-and-register-the-vtdm-appliance
A VMware ESXi 5.1 or later is required to host the appliance. VMware Workstation is not supported. A VMware vSphere Windows client is required to deploy the OVA file.
If you have any issues, I would recommend looking over our vTDM troubleshooting page here: https://docops.ca.com/ca-test-data-manager/4-3/en/virtual-test-data-management-vtdm/vtdm-troubleshooting
Best regards,
Taylor
