Problem:

Failed to install VXDIAG VX Manager driver on Windows 11 Pro operating system.

It reported an error “Load SDK Dll failed”. Any solution?

Solution:

It’s a system issue. Required DLL files are missing on the pc.

If Windows 11 is missing SDK DLL files, you can try running the System File Checker (SFC) to scan and repair corrupted or missing system files, including DLLs. You can also reinstall the Microsoft Visual C++ Redistributable Package or the specific program that is causing the issue. In some cases, enabling the .NET Framework 3.5 in Windows Features might help.

Or change to another laptop and try again. Win 10 is better.
