  2. This version of StarForce DRM does not work on Windows 8.1 or Windows 10.[3][4] For supported versions of Windows the StarForce driver may need to be updated manually using SFUPDATE.
  3. 3.0 3.1 When running this game without elevated privileges (Run as administrator option), write operations against a location below %PROGRAMFILES%, %PROGRAMDATA%, or %WINDIR% might be redirected to %LOCALAPPDATA%\VirtualStore on Windows Vista and later (more details).
  4. 4.0 4.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/2590/ in addition to or instead of this directory. The app ID (2590) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
