Loadlibrary Failed with Error 87 Fix | The Parameter is Incorrect

The error “LoadLibrary Failed with Error 87: The parameter is incorrect” typically occurs due to issues with graphics card drivers or the system’s graphics configuration.

Common causes include corrupted or incompatible GPU drivers, especially with AMD graphics cards, or problems with parameters passed during driver or application loading.

Common Solutions:

1. Restart your PC: Force shutdown by holding the power button for 8-10 seconds, then restart to clear temporary glitches.​

2. Update or Reinstall Graphics Drivers: Use Device Manager to update the display adapter drivers automatically or manually download the latest drivers from the AMD or NVIDIA website to ensure compatibility.​​

3. Rename AMD DLL File (for AMD GPU users): Rename the file atig6pxx.dll in C:\Windows\System32 to atig6pxx.dll.bak to resolve conflicts with certain AMD drivers.​

4. Run System File Checker Scan: Open Command Prompt as administrator and run sfc /scannow to detect and fix corrupted system files impacting drivers.​

5. Check GPU and OpenGL Settings: Tools like GPU-Z can confirm whether OpenGL and OpenCL are enabled on the AMD GPU; incorrect configurations can cause the error.​

6. Disable and Re-enable Integrated GPU: For systems with hybrid graphics (e.g., AMD integrated + NVIDIA discrete), disabling and re-enabling the AMD device in Device Manager can temporarily fix the error.​

Additional Notes:

• The error can surface when using external monitors connected via USB-C with AMD integrated GPUs, and forcing applications to use an NVIDIA GPU may help.​

• Ensure Windows and all drivers are fully updated, and BIOS updates are applied if recommended.​

• If the problem persists after these steps, consider consulting specialized support for your specific software (e.g., ArcGIS Pro) or hardware.​

In summary, this error is mostly due to GPU driver issues or system graphics settings. Start with a system restart, update/reinstall drivers, rename the AMD DLL if using AMD cards, and run system checks to resolve the issue.
