Halo 2 download and install

http://www.ddgamez.com/2013/06/halo-2.html
1. Mount ISO / Insert disc
2. Run Autorun / Startup.exe
3. Select "Customize game install"
4. Enter installation path ("Crogram FilesMicrosoft GamesHalo 2" by default)
5. Select "Full install only, do not start"
6. When the game asks for activation, skip this step
7. Continue / Finish installation
8. Optionally apply the update patch #1 (if you feel offended by accidental nudity )
9. Copy the provided cracked files (startup.exe/MF.dll) to your installation folder
  (the one chosen in step 4)
10.Enjoy !
Note:
If you want to play the game without getting the annoying activation nag,
make sure you use the shortcut on the startmenu or run halo2.exe directly.
If you run it from the autorun of the disc you will still get the nag.
