Hello, Happy Holidays. I am running Windows Vista home premium. When I right click a folder, then go to properties, then under the security tab and hit edit, there is a list of allow or deny boxes to check - the first one being full control. This list is entirely grayed out to me. I cannot check or uncheck anything. I believe I am getting error 1303 when trying to install updates and addons to certain programs because I do not have full control over anything. How can I enable this option? Thanks.
