Issue with ArcMap 10.5 (and above) with Windows10. For some reason I have been getting the following error when trying to start an instance during a remote desktop session (most probably related to the graphics card).

LoadLibrary failed with error 87:The parameter is incorrect.

I found that I actually had to DISABLE the group policy for "Use hardware graphics adapters for all Remote Desktop Services sessions" listed below.

Enabling did not resolve it--disabling and restarting did. The other two policies had no effect.

Here's how I solved the problem (Edit Group Policy tool from Control Panel):

  • Right click on Windows start menu and select Run (or windows+R)

  • type cmd

  • type gpedit.exe

  • go to "Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment"

  • set the following parameters to Enabled

    • Use hardware graphics adapters for all Remote Desktop Services sessions

    • Prioritize H.264/AVC 444 graphics mode for Remote Desktop Connections

    • Configure H.264/AVC hardware encoding for Remote Desktop Connections
