--- Comment #11 from Andrew Nguyen arethusa26@gmail.com 2009-07-20 13:46:01 --- I don't think this is actually a bug, but rather intentional behavior from the installer. Many of the SAPI 5.1 components and registrations are already present in XP RTM, and the conditions in the installer for many SAPI core components specify "VersionNT <= 500 or Version9x", which excludes XP. This should thus be closed invalid.
