Reason for Re-issue: Subsequent to the release of this bulletin, an
issue was found related to the update's installer. Specifically, an
issue was found affecting customers who had applied this security
update and then later uninstalled Windows Media Services and then
re-installed Windows Media Services. These customers could not
successfully apply the security update to the re-installed instance
of Windows Media Player, thus leaving them vulnerable. This issue
only affects customers in this specific scenario.
Customers who have uninstalled and re-installed Windows Media
Services should apply the new version of this security update. All
other customers need not take any action.
