Titanfall 2 doesn't start

I believe that the missing pair of cores, or at least the capability of emulating a total of four cores, will completely block you from access to this game.

Titanfall 2

Minimum:

    OS - Win 7/8/8.1/10 64bit
    CPU - Intel Core i3-3600t or equivalent
    RAM - 8GB
    HDD Free Space - 45GB
    GPU - NVIDIA Geforce GTX 660 2GB, AMD Radeon HD 7850 2GB
    DirectX - 11
    Internet Connection - 512Kbps or faster

So why the game wouldn't tell me that? Is there no way to play below minimal specs? 

The game's minimum requirements are for only moderate frame rates, medium resolutions, and the lowest of graphics settings.  That means 35-40 FPS animations.  Any slower than that looks as jerky and awkward was old silent movies from the 1920s, and the developers wouldn't want anyone to "play" games that way, sorry. 

This is known as "respect to your user". It'll good if developer have it and bother to notify user with some error message on start.

Notification is at Point of Sale.  Digital sale pages at Origin include the system requirements via an easily referenced link.  Retail sales boxed sets have the requirements clearly printed on the package.  Those are the industry standard, and I see no justification in anyone arguing it's not good enough. 

My grandchildren have no trouble with it, nor do I. 

It's been that way the entire 35-36 years I've been playing computer games, and I always found it entirely sufficient.

And what if I simply don't understand anything in PC specs? What if my grandson just gave me a PC and bought this game? Doesn't I deserve a simple error message on start which will notify me about "game wouldn't start"?

for own risk u can try lunch it using dualcore fix...

Are you referring to something (perhaps from Intel) intended for the Pentium versions of CPUs without any Hyperthreading capability?  It's not that reliable overall, is it?  But for a dual core AMD processor, even less so, wouldn't it be? 

Google didn't find anything when prompted to search for anything like that.
