Fallout New Vegas won't launch (Fixed)

[ẒØÐ]

I just downloaded FNW Ultimate Edition. When I try to lauch it, it shows the small box "Preparing to launch Fallout New Vegas" as if it was going to load it. Instead, It opens and closes rapidly, trying to launch it over and over until I close it. It tells my friends the I start and stop playing it rapidly. I have uninstalled and reinstalled, after doing a "Verify Integrity of Game Cashe" and it tells me one file is wrong. It doesn't tell me which file, but it also does not fix the file. Please help!

Solution: I disabled my uac and it ran just fine.

restart steam to get the file to valadate...

make sure you right click and run both of these as admin and they finish.
C:\Program Files (x86)\Steam\SteamApps\common\Fallout New Vegas\Redists\
vcredist_x86
and
DXSETUP

User Account Control. You can turn it off somewhere in control panel or just search it in your start bar, depending on what Windows you have.

Hey, just wondering, but, mine only works if I switch the UAC on and off multiple times, any ways to stop this? i really just wanna play the damn game.

[Saint Floyd]

also, i cant play it multiple times after i restart it, it is only one time

[talgaby]

Then probably your system itself needs a reinstall, if it is acting up like this. But your problem is on the OS side, not on the game.

[Saint Floyd]

so i would need to reinstall my OS? how exactly would I do that?

[Saint Floyd]

never mind, thanks for the help

Disabling UAC didn't work. Try turning off you antivirus software.

IMPORTANT YET SIMPLE: Make sure you guys have updated drivers and make sure Nvidias Geforce experience hasnt uninstalled its self. It uninstalled itself and i didnt know it but after i reinstalled it and updated my drivers it started working. I was having the same issue with fallout 4 and this also fixed it.

I did everything this said and it still did not work

THANK YOU MMCHAOS !! I pressed DXSETUP in the FNV - Redists - directx folder and installed it, now it will launch! Thanks!

This is a joke I just purchased the game myself & I'm having the same issue. Mind you its not surprising, I forgot why I left PC gaming only to come back & remember oh yeah! this crap
