Addressing Incorrect Parameter LoadError 87

The “LoadLibrary failed” error is specific to AMD machines and can occur due to several reasons. The common contributing factors are outdated or corrupt AMD graphics drivers, issues with the corrupt graphics driver module, and app-specific issues.

You can often fix this error by renaming the atig6pxx.dll file, a graphic driver module for your graphics processor. If not, updating or rolling back your graphics driver should also help.

Here are a few troubleshooting steps to help you fix the “LoadLibrary failed with error 87: The parameter is incorrect” issue on Windows.

1. Perform a Quick Restart

At times, the LoadLibrary failed error can be a temporary glitch. However, the error dialog won’t let you close it or access anything else on your computer. In this instance, a force shutdown is useful. Make sure that you don’t have any important and unsaved work which may be lost after an abrupt restart.

Next, press and hold thePower button on your computer to force a system shutdown. Then, press the power button again to restart your PC. If you see a black screen, leave the device idle for a minute or two before you proceed to the next steps.

If the error persists, disconnect your external displays connected to your system via HDMI or DisplayPort. Then, perform a restart and check for any improvements.

2. Update the Graphics Device Driver

If you have a fresh Windows install or using a new system, your computer may be missing the necessary driver for the display adapter. This may cause your display adapter to malfunction and stop working.

To fix the issue, check and update your graphics drivers on Windows . If you have a dedicated GPU, use the GPU management tool from the manufacturer to download the update. You can also download the newer updates from the GPU manufacturer’s website.

3. Perform a Driver Roll Back

This error is often due to the issue with your display adapter and mainly with the AMD machines. If the error is triggered after a recent driver or OS update, check if your graphics device has received a newer update. If so, you can perform a driver rollback to reinstall the older driver.

You can perform a driver rollback using Device Manager . This should work irrespective of the Windows version you are running. However, if the rollback driver option is greyed out, it means Windows doesn’t have an older version that you can go back to and reinstall.

Corrupt display adapter drivers can also trigger “LoadLibrary failed with error 87”. To fix the issue, you can uninstall the display driver from Device Manager and then perform a reinstall.

To uninstall a display adapter driver:

1. PressWin + R to openRun .
2. Typedevmgmt.msc and clickOK to openDevice Manager.
3. In Device Manager, expand theDisplay Adapter section.
4. Right-click on your graphics device and selectUninstall device .
5. SelectAttempt to remove the driver for this device option and clickUninstall .
6. Once done, restart your PC.

You can now reinstall the driver from the GPU manufacturer’s website. If the issue persists, check if the GPU drive is completely removed. If not, you can use Display Driver Uninstall to completely remove GPU drivers .
