Vmware Vsphere and EXSi install with windows 2012 and redhat linux in our office and create cloud with live ip.?

Hey guys, so virtualization is new for me and boss finally let me setup a test server. I installed VMware ESXI 5.5 and I'm have an issue and I can't find help online that is useful. He told me to install an Ubuntu virtual machine and I did. I have the ISO for it but it keeps saying the above error. I'm on a 32 bit machine trying to install a 32 bit virtual machine with the 32 bit ISO. Thanks in advance.
