The K-Lite Codec Pack is a free collection of codecs and related tools. Codec is short for Compressor-decompressor. Codecs are needed for encoding and decoding (playing) audio and video. The very user-friendly installation is fully customizable, which means that you can install only those components that you want. There are three versions of the K-Lite Codec Pack: The Basic version, who fits on a single floppy disk, contains only the most essential codecs and related tools. The Standard version contains everything what is needed to play all the commonly used formats. The Full version contains even more codecs and also has encoding support.
The text in black applies to the Full, Standard and Basic versions, the text in green applies to the Full and Standard versions and the text in red applies to the Full version only.
It is highly recommended to uninstall all existing codec related software before installing. This way your system stays clean and potential problems will be avoided.
