though i can get the game to run by enabling the windows built in 'administrator' account and logging in and playing from that account, if you like to play online in simcity, then it is super risky (imho).
Since EA seems unwilling to fix or even acknowledge the issue that we are all having, i am at least willing to try and troubleshoot it with the community.
but before i did any further troubleshooting.... i disabled the built in administrator account once again. then i brought up the windows command prompt (powershell would proabably do as well, but i am a DOS man.) then i navigated to the games install directory and tried loading it using windows SUDO command. if the cause was really any sort of admin permission issues or anything like that, Sudo should have blown all that away and allowed the game to load. however..... IT DID NOT. (command used was 'sudo .\simcity.exe -e --inline' from 'c:\program files(x86)\origin games\SimCity\SimCity\')
NOTE
when i made the upgrade rom EA origina to EA desktop, my existing EA software library got imported over to EA desktop, but they still reside in the old EA Origin location over in program files(x86).
my next stop was to watch the taskmanager as it tried to load simcity. the first thing i noticed is that a process that gets opened when the game IS able to launch was opening for a split second then closing. this file was one of EA desktops files, called 'EAGEP.exe'
a google search did not turn up anything helpful about the file, so i dug into my system further. I went to 'C:\programdata\EA Desktop\Logs\' and found a bunch of log files. but the two i was most interested in were the files EAGEP.log and EAGEPVerbose.log. looking at the first log i found the exact moment when the issue seems to occur.

it seems that when we make a request to launch the game the EA app 'phones home' and the app sends back a 'go ahead' signal. but by the time the signal is received the EA desktop client has given up trying to launch simcity.
if i am reading the logs correctly, the EA desktop is waiting about 3 seconds (3000Ms) before giving up, during which we have to click the 'okay' button for allow the game to launch the game to launch with administrative permissions. no matter how fast you click, that is too little time to get through the process AND have the traffic go back and forth before the connection times out.
