I'm having this issue, too. I've tried all the fixes suggested here, and on the forums, but can't get the game to load. For some reason the installer isn't downloading it seems. My error code is a different one, but I did get this code at first. Now I get:
"service initialization failed (0x0175dcbb)"
Mac, everything up-to-date, have tried restarting, uninstalling, and everything between. Running latest OSsierra.
Exact same error here; "Service initialization failed (0x0175d824)" on Windows 10 PC.
I bought the game today and cannot play it.
I have never had Origin on this PC so it is a fresh install of not only Origin but the game itself: Sims Medieval.
This is a vanilla game with NO mods at all however I also tried the usual fixes listed previously (clearing out files, compatibility mode etc).
Any help would be greatly appreciated.
Thanks for this advice (#8 above). I opened up Nvidia Geforce Experience and got it to optimise the graphic settings of the game. I noticed that the game defaulted to a resolution that wasn't 1920 x 1080 (my monitor/gaming resolution). Might this be the cause for some people? If you haven't GF experience see if you can access the basic .INI file (PC > documents > EA > Sims Medieval > options) and set the resolution in there (?)
