I've tried here

loExcel = newobject("Excel.Application")
	with loExcel
		.ScreenUpdating = .f.
		.DisplayAlerts = .f.
		.WorkBooks.add()
*	    .Quit()
		.visible = .t.
	endwith    
	    loExcel = null 	
RELEASE loExcel	

and it worked fine for me - Excel 2007.

Could it be corrupted installation ?
