I have been playing Tom Clancy’s HAWX since the release of the game. I am actually a big fan of Tom Clancy’s series, however I finally upgraded to Windows 10 and had to reinstall the 8 years old game. After installation I tried to launch it and I got d3dx9_39.dll is missing from your computer error. The error dialogue suggested me to reinstall the application to fix the issue. The issue hasn’t gone after the reinstallation, even though, it appeared in other applications as well. I really didn’t want to come back to Windows 7 just because of one game, but it looked it is the only solution to get rid of d3dx9_39.dll is missing error.
I found that the d3dx9_39.dll library is the DirectX library for older versions of DirectX. Since the Windows 10 comes with DirectX 10 preinstalled it doesn’t have DirectX 9 libraries which are necessary for old games such as Tom Clancy’s H.A.W.X. Actually on the Internet I found a lot of useful information and lots of reasons why d3dx9_39.dll error could’ve happened. Anyhow, fix d3dx9_39.dll is missing in Tom Clancy’s HAWX I just downloaded the missing library from https://fix4dll.com/d3dx9_39_dll and installed it in C:\Windows\syswow64 folder and then registered in command line. The detailed installation guide is provided on the website. Keep in mind that if you are running different version of Windows you probably will have to copy into different location.
Have a fun playing Tom Clancy’s HAWX without d3dx9_39.dll is missing error. Feel free to share this guide with your friends.
