When installing Codecs in Windows XP Professional with Service Pack 2 build 2135-2144 they don't work. Installing process goes normal but after setup there is no information in Add/Remove Programs but when looking in Device Manager\Video Codecs there are all the codecs installed. And no Video file and DVD can be played. In Service Pack 2 build 2096 there is no such problem.
By the way the same is with Codecs Pack All in 1.
Can anyone tell what is the problem ?
