Sodapop, you're not missing anything. No CODEC needed to update LR, PS or PSE, but CODEC updates are needed to open RAW files from new camera releases in Windows. However, the OPs issue was not being able to open his D4s files in WINDOWS and for that he needs to update his CODEC files from either Microsoft or Nikon.
LR5 will need to be updated to use on the D4s raw files.
