LoadLibrary failed with error 87: The parameter is incorrect

Error Message

When opening or creating a project or map document in ArcGIS Pro or ArcMap, the following error message is returned:

Error:   
LoadLibrary failed with error 87: The parameter is incorrect.

Cause

This issue occurs due to the machine's graphics card configuration.

• The graphics card driver is out-of-date.
• There are conflicting graphics cards in the machine.
• If using Remote Desktop Protocol (RDP) to connect to a remote machine, there could be a conflict between the video card specified by the RDP connection, and the one used by ArcMap on the remote machine. RDP is connecting by default to a built-in Intel video card, and not the video card used by ArcMap.

Solution or Workaround

Depending on the cause, either:

• Update the graphics card driver, or
• Refer to Problem: Graphics card conflict may cause ArcMap to crash to resolve the issue of conflicting graphics cards, or
• Follow the solution described in Problem: LoadLibrary fails to load with error 126 or error 87 when working remotely over RDP
