Fallout 3 xlive.dll file download
Right, the way to fix this is to get the g4wl installer, it should be on the fallout 3 disc somewhere, the installer should be called something like "XLiveRedist.exe". Install that, then fallout 3 should work. Quite a major update has been released and you may need to wait for it to download it, but fallout 3 may have the latest installer. To fix the error, you need to copy the missing xlive.dll file to your system or replace the corrupted dll file with a working one by following the instructions below. There are 4 different versions of the dll file available for download with sizes between 11.11MB - 14.74MB.
