Since you have deleted the exchange server on which upgrade had to be done. Now uninstallation will also not succeed properly since the actual server container in ADSIEDIT has been removed. Whether its installation or uninstallation the setup looks at the server container in ADSIEDIT and this server container is also replicated on all DCs.

So now you will have to do a manual exchange uninstallation. You can follow below article for manual exchange cleanup and then setup a new exchange install if you require.

  I've deleted :
  
  CN=Configuration,DC=DOMAIN,DC=LOCAL
  CN=Services
  ->; DELETE
  CN=Microsoft Exchange
  CN=Microsoft Exchange Autodiscover
  
  Here I did not find an exchange server in groups and objects
  
  CN=Default naming context,DC=DOMAIN,DC=LOCAL
  ->; DELETE
  CN=Microsoft Exchange Security Groups
  CN=Microsoft Exchange Security Objects
  
  in the registry all deleted (MSExchange*), directory removed
  in IIS Manager all deleted
  
  and again stopped installation at step 7 (as in the screengrab above)

    Did u uninstall IIS from the exchange box after manual removal of exchange.
    
    Then after uninstall of IIS you need to reboot and install IIS again using prereqs.
    
    Then install exchange as new.
