I wanted to play Gmod, after getting a new laptop. D3DX9_40.DLL is missing it says. I've downloaded it and put it in the files and it says it's still missing. I've done the installer in the June 2010 file and it says Installation failed. I did another Direct X Updater and that also failed. I did a Direct 9 installer that I believe would of fixed it if it did not fail installation. I've been looking for hours and I can't fix this. I am not good with this, and don't wanna break my new laptop that was a gift after my old one broke. It is Windows 10, and I really do not want to install a older Windows/ restall Windows 10. Help.
