Hello OcUK,

Long story short. The missus has gone, giving me a rare chance at a gaming evening. I really fancy playing my old copy of Fallout 3 but it won't run.

It will open the launch app but it won't let me start the game. I've downloaded the latest update from the official website but I still just get this error:

The application was unable to start correctly (0xc0000005).

It worked fine on my old rig but I think there is a problem with modern CPU and this game. I have a 2600k. I've tried the below along with compatability mode and several re-installs.

Find the line: bUseThreadedAI=0
Change it to: bUseThreadedAI=1
Add another line after it and insert: iNumHWThreads=2

Google has been exausted and I'm out of ideas.

If someone brings a fix to me quickly, saving my evening, I'll send you a game via steam. I have a few gifts on there inc. LFD2, Limbo and PvZ.

I'm using an onboard sound card and the driver was downloaded and installed about 2 weeks ago.

My GTX570 is running stock, no afterburner and only one screen.
 
Yes it's on steam. That was one of the first things I tried. I've tried everything suggested here, still no luck. :(
 
Thanks for all the suggestions guys, unfortunately I'm still unsuccessful, so have decided to start HL2 downloading and I'll get my nostalgia fix from there.
