Sims 4 not running

Update - I installed on my laptop, same OS (win 8.1 x64) same account (using a microsoft account to log in) - game works just fine, no issues at all. I'm using AVG on both the PC and the laptop. 

Attempted once more on the PC in safe mode, can't get it running. 

The only thing I can think of that's different between my two machines is that my PC has recently been formatted (maybe missing an essential DLL?) 

Or maybe it's a registry issue (My PC has many origin games installed, my laptop had none). 

Any other suggestions? 

Does the laptop use the same VPN? I know you mentioned disabling it, but I'd like to discount it completely.

Did you use ccleaner before? http://help.ea.com/en/article/how-to-use-ccleaner-to-fix-pc-issues/

You mention cleaning the registry, did you do this between installs?

As well as possible missing updates, it might be worth running sfc, on the offchance there's an OS issue.

Laptop does have the same vpn, yes (not active on either machine atm)

I did use CCleaner while in chat with support (no effect) 

I did not do this between installs

There are a few updates the laptop has that the PC doesn't, these include microsoft xna framework, and the C++ x64 (I have the x86)

Aside from that both have the exact same stuff installed.

I currently uninstalled origin & all my games - then will do a registry clean, and reinstall. Once I try that and see if it works I'll see if I'm missing updates some where (sfc indicates I'm fine) and HOPEFULLY something will work. 

@stargrace Heya,

As you are doing the reinstall anyway, it would be best if you do a clean boot once more prior to starting the installation. Additionally also check that your security software is turned off as well just to ensure that nothing is being blocked. Some of the usual suspects are summarized here: http://help.ea.com/en/article/programs-that-may-cause-conflicts-with-origin/

It might also be worth to ensure that User Account Control is enabled and set to notify: http://windows.microsoft.com/en-ie/windows/what-are-user-account-control-settings#1TC=windows-8

Once all of that is done, go ahead with the download and installation of the Origin Client once more: https://www.origin.com/download

Let us know how you get on.

Cheers,

Nils

No luck with any of the above mentioned. Still won't run. 

reinstalling graphics drivers had no effect. running the system file checker found nothing.

Its still not working, any more ideas?
