Just before the release of Fallout 4 New Vegas I’ve decided to play Fallout 3 to get into the story. Bought the game on steam and installed it. When I tried to launch fallout 3 game on steam I got xlive.dll is missing error. I never had errors in games in steam library. I verified cache of the game and files, but the xlive.dll is missing from your computer error still remained. Well, I am not giving up quickly so I went further and started to search on the Internet how can I fix fallout 3 xlive.dll is missing error on steam. After few hours of searches I finally found the solution and it worked for me.
Since, the reinstallation of the fallout 3 on steam didn’t fix the xlive.dll is missing error obviously this error is not related with game but with operating system. On some forum I found that xlive.dll might be removed by antivirus or simply damaged by other program in my system and that’s why I have xlive.dll is missing problem. So, to be able to start fallout 3 on steam without xlive.dll is missing error all you need to do is just to download and install the file from here: http://fix4dll.com/xlive_dll.
This fixed my xlive.dll is missing in Fallout 3 steam version. Probably it will work for other games too. I don’t know if it will be useful but I am running Windows 7 64 bit. Enjoy playing!
