How to fix x3daudio1_7.dll is missing error on Windows 8

I recently purchased a used desktop which came with Windows 8. I wasn’t ready to upgrade to windows 10, partly because I think it’s too soon and also because of all the spying rumours circulating. However, I didn’t want the Windows 8 either, so I decided to upgrade to the Windows 8.1 64 bit. I was unable to run my games and apps after the upgrade. I kept on receiving a system error message stating that “The program can’t start because x3daudio1_7.dll is missing from your computer. Try reinstalling the program to fix problem” each time I tried launching the program. I wasn’t ready to reinstall every program on my PC, so I decided to go online in search of a solution. And I discovered a solution to the x3daudio1_7.dll is missing error.


The x3daudio1_7.dll is a part of Microsoft DirectX for Windows program developed by Microsoft Corporation. I don’t really know why it is necessary for every program to have this library, but if it is damaged or missing, it’s impossible to run programs. This library happens to be quite sensitive, since it is used by different programs at the same time making it a prime target for viruses. This means your antivirus can delete it and it can get damaged or corrupted as a result of excessive use, either of which can cause the x3daudio1_7.dll is missing error. All you need to do to fix this error is to visit and download and install the x3daudio1_7.dll file.

It is quite easy to install x3daudio1_7.dll, all you have to do is to copy the file and put it in the appropriate location depending on the operating system you’re using. However, you can get detailed instructions on how to install it on the download page. Feel free to suggest this guide to your friends who have the same problem.
