Importing OVF file error

[aa2017]

Trying to create a virtual appliance and Importing the OVF file gives me this error. After I changed the memory size to be 8192 it gave me the second error that is checksum. Any ideas guys what am I doing wrong? Also, the IP address and other details will be specified later when the virtual server is up and once I login or should I enter all that before itself, since it is going to be static.

The checksum will no longer match if you modify the ovf-file.

Either you rebuild the OVA/OVF from scratch or you  import the vmdks with vmkfstools -i and create the vmx-file manually.
