Hi,

I've recently built a new PC:

Intel Core i5 750 2.66GHz
MSI P55A Fuzion Socket 1156
RAM Kingston 4GB DDR3 1600 MHz
MSI GTX460 Hawk
OCZ Stealth Xstream 600W
XP Home SP 3 - with all updates

and am having issues getting Fallout 3 to work. I have the game previously (borrowed from a friend) and it worked on my old setup. However, I have now purchased it new from Amazon and am having a few problems.

When I first inserted the CD it didn't auto-run, then when I went into my computer and clicked on the F: drive for the DVD/CD rom I got an error saying the application may not be configured properly and I should try reinstalling. I looked in event viewer and am getting a 'SidebySide' error. The event ID given is 59. I have already tried installing Microsoft Visual C++ 2005 Redistributable Package, as I read on Google that this resolved sidebyside errors for some people - unfortunately it hasn't worked for me.

I had to right click on the F: drive and select open to bring up the contents of the CD and nstalled the game by running the setup file. Even after doing this I still can't run the game. I get the same error message when I click on the F: drive from within my computer, or if I go to start>programs>fallout 3.

Has anyone experienced this? Does anyone know how to fix the problem?

Cheers,

Dave.

Just to add, I have tried installing the patch as well, but get the same error half way through the install.

Cheers.

Tried the Multi-Core Fix?:

Find your .ini file in your My Documents\My Games\Fallout3 folder ...it is the configuration settings file named FALLOUT

Open it with notepad and do a CTRL+F to search for the line

bUseThreadedAI=0

.....change it to =1


and below that line add this line

iNumHWThreads=2

I managed to get this working last night, after numerous windows updates were automatically downloaded and installed.

The multi-core 'fix'', whilst apparently a fix, seems stupid to me. You shouldn't have to effectively limit your hardware to get the game to work, especially when the recommended system is a dual core.

Thanks anyway.
