Modern Warfare 2 and Steam issue

December 2016


  • I just bought Modern Warfare 2 this morning.
  • But, I feel initial disappointment about installing the game, which requires going through STEAM !
  • I find it very heavy as a process, especially when you have a very slow connection and the game, set installation over 13h, is only 15% of downloading STEAM!!!
  • Do you have a solution to install this game without going through steam?


  • Completely close Steam (even in the tasktbar)
  • Go into the Steam directory (for me C: \ Program Files \ Steam).
  • Locate and rename the ClientRegistry.blob file (eg ClientRegistryPAS_BON.blob)
  • Reinsert the DVD in the drive -> Re-install
  • Steam will restart ! You'll have to do a mandatory update of approx 1 min download before the installation process is done from the DVDs ->

Thanks to zefin for this tip.
