Error firing vbld_BuildStarting event

[bwilder]

Thanks,
The full script is posted below and the failing method appears to be the CreateObject() method in the vbld_BuildStarting() method. Do you have any thoughts on what would causing this or how I would go about fixing it?

Sub CreateShortcut(target, sname)

	Set objWshShell = CreateObject("Wscript.Shell")
	
	' Read desktop path using WshSpecialFolders object
	strDesktopPath = objWshShell.SpecialFolders("Desktop")
	
	' Create a shortcut object on the desktop
	Set objShortcut = objWshShell.CreateShortcut(strDesktopPath & "\" & sname & ".lnk")
	
	' Set shortcut object properties and save it
	objShortcut.TargetPath = target
	objShortcut.Save
End Sub
