DirectX websetup installs some DirectX components which does not included in DirectX 11.
In addition, we cannot uninstall or reinstall DirectX 11.
You may run dxdiag.exe to check the current DirectX version.
To troubleshoot the issue, I would like to suggest you update the display card driver for Windows 7 first and test the issue in Clean Boot.
If the issue persists, I also would like to suggest you run System Restore to check the issue.
