I have recently bought a pre-assembled desktop computer. Everything seemed to be working fine until I started getting some strange error. Whenever I try to open certain programs, I get the d3_dx9_43 dll missing error and the program crashes. How to get past this?
What you are getting is a dll file error. Dll files are shared files and therefore are not linked with the program that installs them on the computer in the first place. Dll errors are pretty common and relatively easy to solve.
First, you need to check your computer for viruses and malware as these errors are often caused by corrupt files. To solve this error, all you need to do is find the missing dll file on the internet and download it. Install it on the computer and place it in the system folder. Restart your computer and the problem will be gone.
