Installing On XenServer 7.2

Good day!

I just downloaded the OVA template for both CentOS and Ubuntu, and both VMs have failed to import.

Here are steps I selected when importing:

Select File
select Location
Select Storage
Select Network Target
Security: left Verify Manifest Content unchecked
OS Fixup Settings: radio button on don’t use Operating System Fixup
Transfer VM Settings: left on DHCP

Any help you can provide, i would be most grateful!
