computer keeps informing me that Microsoft security update for office 2003 No KB2289187 is waiting to be installed. When accepting, it states "installation failed". Gives Error code 1603
. But it is already 9installed.
Go to that update website, and do a custom install. It should list each item that is available for download. Click on that particular KB, and choose not to install it. There will also be a box to check to never be notified about it again.
