Hey guys, so i been dealing this problem ALL DAY, and i was legit about to sorta cry and give up, and i installed/ updated my Geforce drivers, and installed/reinstalled GeForce experience, i did this about 2-3 times for each, the drivers and the experience as well, i also restarted my PC, and i took notes to edit from the GeForce Experience, edit you're window type, i choose windowed, instead of full screen, the 3rd TIME AROUND, this was my last time trying, and surprisingly IT WORKED! FINALLY! its in windowed form, and all updated, drivers, msi, cpu. even my malware i updated. And before this, i tried the force add on folder/virus protection and added Ts4_x64 that NEVER worked so i removed all that, defaulted back to the original, and re did the STEPS. installed/updated drivers, the game itself, and finally worked the 3rd time around. SO all i have say DONT GIVE UP, MAYBE try 3-4 times updating/ removing/ restarting you're PC over and over until finally get it working, SEEMS that WINDOWED MODE, really was the last thing to HELP me get my game to START UP. NOW i did get a error about my video cards BUT the game is working SO i dont understand what could still be wrong, i want to restart my PC again now, to make sure no problems when i do turn it off and get off, and restart and come on to play Sims the next day, BECAUSE if this became a problem everyday, ill be done with the SIMS lol i dont want to be, but today was HELL trying figure this out and finally PLAY and i was SHOPPING for CC all day until I realized my game never, ever was going to work apparently, BUT now IT DOES. SO BOO YA!
I HOPE THIS HELPS ANYONE/EVERYONE OUT! Enjoy.
