      Teddun Download MW3 from steam, don't use Tekno, it's an older version of MW3 which won't work. We use the latest version from Steam. https://forum.plutonium.pw/topic/448/how-to-download-the-iw5-base-game/

                      We don't support Windows 7, it's reached End Of Life and is a security risk. We suggest upgrading to Windows 10. If you have Windows 10, create a separate support thread so we can easily provide support.
