The patch can only be applied on top of the GM version which is 4.0.0.529, or one of the previous patches. So you will need to install 4.0.0.529 first, then perform the update.
I upgraded as requested, to version 4.0.0.529 and tried applying the update 4.0.2 and 4.0.3 but neither worked. follows the image attachment from the message that appears when I try to install the update. the same message appears in both cases.
