• If you have the original release without the expansion pack install the Alpha Centauri v4.0 update and then the compatibility-patch.
• If you have the Planetary pack or Laptop pack only install the compatibility-patch.
• If you have the original Alien Crossfire release install the Alien Crossfire v2.0 update then the compatibility-patch.

Now you can install the unofficial patch of your choice.
