Football Manager 2010 Activation Methods

Football Manager 2010 has two installation delivery options; STEAM or Offline.

STEAM

STEAM requires internet access but not the game DVD. It installs patches and data updates automatically.

Offline

The offline system does not require internet access but you need to have the DVD in the DVD drive at all times to play the game. Patches and data updates will have to be downloaded / applied manually.
* If at the installation stage an internet connection cannot be detected by default the game will install via offline system.
