I have a virtual ESA appliance setup and I need to license it. I requested a 45-day demo license for it. However, when I tried to attach the license to my virtual ESA appliance it gives the error "Could not load the license file in the appliance because it did not contain a cloud feature key" as can been seen in the image below.
Please an urgent help with this would be greatly appreciated, thank you.
