Hi,
To help you suggest steps to resolve the issue, I would appreciate if you could answer the following questions:
1. What version Microsoft Visual C++ is installed on the computer?
2. What is the exact error message about .dll error and when you install DirectX setup?
Mostly, these kinds of error can be caused by two factors:
· Runtime components of Visual C++ Libraries are missing.
· Software problem.
**Method 1:**If the issue is caused by #1, you can reinstall the Runtime components of Visual C++ Libraries to resolve the problem.
Microsoft Visual C++ 2010 Redistributable Package (x86)

Microsoft Visual C++ 2010 Redistributable Package (x64)
**http://www.microsoft.com/en-us/download/details.aspx?id=14632**
If the issue still persists after installing above package (install anyone as per the version of Operating System you are using), the issue should be a software problem.
**Method 2:**I suggest you take a Clean Boot check whether it is a software conflict issue. If not, it is still recommended to address the problem with manufacturer support.
Place the computer in a clean boot state and then check if it helps. You can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.
