I am using windows xp professional SP3 and I am currently trying to install Microsoft XML parser. After unsuccesfully trying to install MSXML 6.0, MSXML3.0 i finally found that for SP3 the version is MSXML 4.0 SP2. In another article's heading I saw taht in XP SP3 the XML parser is built-in. The problem now is that wnen trying to uninstall the versions whose setup couldn't be completed. MSXML 6.0 service pack (KB954459) is on the list in Add or Remove Programs in the Control Panel, but I can not remove or repair it. How can I uninstall this sofware?
