The K-Lite pack does not work. See why your K-Lite pack does work anymore? My K-lite codec containerized stopped working a while ago, I used to get the icons in the tray at the bottom, but it stopped starting up with windows media player.

You are going to need to find out what type of file you are trying to play. This you can do with codec sniper. Dont install coded packs as they are not very good. Find out what you need first then search the internet for that the video file needs.
When these types of problems occur the next step is to scan you computer for a virus or for malware. This does cause problems as well as toolbars which certain software which install without your knowledge. These two steps will normally solve most codec problems.
