This error could be due to the DOS support being enabled. To disable DOS support:
-Go to the "Device Manager"
-Right-click the "National Instruments GPIB Interfaces" and click properties
-Uncheck Enable DOS Support
If you don't have this option, you can also remove the error by starting regedit (Start >> Run, then type regedit) and looking for a registry entry under
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices called NI4882MDosSupportEXE. Removing this registry key should remove the error. Be sure to back up your registry before making any changes to it!
