I see. No I doubt creating the folder or using someone else's would work sadly.
If you haven't tried killing off running apps (especially GPU-tuner related apps as they often have overlays in them), I'd try that.
You may try contacting EA directly here: Perhaps they have a better idea than me.

If you are looking for some more things to try, replace "Garden Warfare" with a game like Battlefield or Battlefront as they use the same engine and often can have similar errors and fixes. I don't want to just start throwing completely off the wall things at you to try but if you are desperate and looking for something to try.... google should return lots of results for those games not launching than it does for GW2 due to them being much larger player base games.

I doubt you would like this idea... but I'll throw it out there. You could partition your hard drive to make a bit of room for Win10, sign up for a free trial from Microsoft's website. Dual-boot the PC 7+10. You can reset the trial completely legally twice, so it'll last a good long while... I know dirty idea but win10 does install quick and with some tweaks like ClassicShell/Start and gutting the consumer apps.. I like it.
Sorry I couldn't be of more help.
Best of luck.
Worked for me !!! Turned off "legion fan control" and game started. But you need to be careful because this can overheat your gpu. Thank you man !!!
