Issues in message news and Dxsetup.exe

Hi experts.
I am seeing this same error message once, perhaps twice in the 2 or 3 months. Also, I have a Missing or corrupted DxSetup.exe problem.
When I tried to install non-essential software programs, this same DxSetup.exe error message occurred. Message is: “Installation failed. Missing or corrupted DxSetup.exe.” I choose to terminate the installation and delete the non-essential software program when the error message window popped up.

Please help. Thanks.
