Same issue here, using the same settings on Windows 10 and a Linux client and the installer hangs at initializing. The log shows nothing useful, it never runs the OVF Tool to actually push the ova to the host. I was able to install a 7.0.3 vCenter using the same settings (literally the cached ones in the installer) without an issue.
I was able to install 8.0 successfully by manually deploying the ova that's in the vcsa directory on the iso through the ESX web client, then connecting to the VM on port 5480 to complete Stage 2.
