Loadlibrary failed with error 87: The parameter is incorrect.

This will usually happen on initial login to the machine/pc or when connecting on remote desktop.

Cause for the error:

  • Graphics Card Driver Outdated
  • Remote Desktop Conflict on Graphics Card Used
  • Conflict Between 2 or more graphics cards in the machine


  • Update the graphics card from Device Manager using Windows Update.
  • If Windows Updates reports you are on the latest version or no updates found then attempt to check for the latest driver from the graphics cards supplier website.
  • If you have more than 1 graphics card, It’s recommended to update all drivers across the graphics cards, but I’d update one graphics card at a time to see which one was causing the issue in the first place.
