If you happen to encounter the error “Python.exe has stopped working” during an upgrade or installation of vCenter Server you may have hit a known issue that VMware is working on resolving. To confirm you are hitting this known issue, reference the vminst.log and the upgradeRunner.log files. You should see the error messages below.
vminst.log (%temp%)

This issue is caused by a NIC on your vCenter Server having more than one IP address. To check if this is the case, go to Network Connections -> Ethernet (Right Click – Properties) -> Internet Protocol Version 4 (TCP/IPv4) (Right Click – Properties) -> Advanced
You will need to temporarily remove all but one IP address on the NIC, rerun the upgrade, and then you can add the IP address back once the installer is successful.

    An additional note, you can’t use DHCP. I use static DHCP in my lab sometimes. My vCenter happened to be a VM that was using static DHCP. This stopped the upgrade with the same error.
