Finally, I bought Fallout 4 in local retailer shop with a great discount. When I came home, I installed the game, but whenever I tried to open the game I was getting system error “The program can’t start because X3DAudio1_7.dll is missing from your computer. Try reinstalling the program to fix this problem”. I didn’t want to reinstall the game that took 1 hour to be installed. I simply made a post on reddit and got a lot of hints from users all around the world. Some even provided me with complete guides, but unfortunately I was not able to fix my game by reinstalling DirectX and Microsoft Visual Studio. Anyway I was grateful for the support. I thought that I will have to reinstall the game, but decided to check my post for the last time and one user advised me to manually install the missing X3DAudio1_7.dll library.
Well, all I can say is that worked like a charm. I just downloaded and installed the X3DAudio1_7.dll library from http://fix4dll.com/x3daudio1_7_dll. After that I was able to run the Fallout 4 without X3DAudio1_7.dll is missing error. And it’s quite logical, if the .dll library is missing why don’t you just install it. The installation process is very simple, you just need to copy the X3DAudio1_7.dll library to proper system folder, more detailed instruction is provided on the downloading page.
Hope this guide was helpful for you and you were able to fix X3DAudio1_7.dll is missing error in Fallout 4. Feel free to like and share.
