The K-Lite Codec Pack is a collection of DirectShow filters, VFW/ACM codecs, and tools. Codecs and DirectShow filters are needed for encoding and decoding audio and video formats. The K-Lite Codec Pack is designed as a user-friendly solution for playing all your audio and movie files. With the K-Lite Codec Pack you should be able to play all the popular audio and video formats and even several less common formats.

K-Lite Codec Pack 3.2.0 : 64-bit

This is a bundle of 64-bit DirectShow filters that can be used together with 64-bit players, such as Windows Media Center. This pack can co-exist without problems with the regular (32-bit) K-Lite Codec Pack.

The 64-bit versions of Windows can run 32-bit software perfectly fine. So it is recommended to use the regular K-Lite Codec Pack when possible. That one contains more, better and faster decoders. You only need 64-bit filters for use with 64-bit applications.
