Installing VM on ESXI Server

I am trying to install HA OS on my server running ESXI. I have freshly installed ESXI and there isnt any other VMs installed. I keep getting the same error: Failed to deploy OVF package: the following manifest entry file (line 1) is invalid… I am trying to install via the OVA file. Any ideas to try?

I was hoping to use the HA OS as my current install over ubuntu wont let me upgrade anymore.
