From time to time I've noticed questions about running Civilization 2 on Windows 7 (both in General Discussion, and this forum), although the problems seem to be with 64 bit operating systems. The purpose of this thread is to present different options for running the game in one location, so that the information is easy to find. To keep this thread short and easy to read, please do not seek technical support for implementing these options in this thread. If you have a game of Civilization 2, the first thing to do is establish exactly what game you have. The early versions of Civ 2 are 16 bit programs, which will not run directly on 64 bit Windows Operating Systems. "Classic" Civ 2 (also known as "Vanilla" or version 2.42) is a 16 bit game, and I think that Fantastic Worlds is also (but I'm not sure). Windows will not even install these games. Th later versions of Civ 2, Multiplayer Gold Edition and Test of Time, are 32 bit programs. These will install on 64 bit Windows, but have a bug with text boxes. If you have a 32 bit version of the program, Mastermind's Patch should fix your problem. If you have a 16 bit version, you have the following options: 1. Upgrade to Multiplayer Gold Edition. 1a.This post (and some that follow it) in the Mastermind patch thread explains how to upgrade to MGE if you have a classic disk. This Thread is a more detailed tutorial. 1b. Buy MGE. You might find a disk online somewhere. Or, this site sells a downloadable version for 5 Pounds. You will get Civ 1 with it as a bonus. I purchased from this site, and didn't have any trouble beyond applying Mastermind's Patch. 2. Use virtualization software to run a different operating system. You can then play classic and avoid the hostile AI. These options are more difficult. 2a. Upgrade to Windows 7 Professional, then use Virtual PC to run XP mode. This will probably be expensive. I personally use this method, but only because my university offered the upgrade for free. When all is said and done, it is very convenient to use, but upgrading the computer may require tech support. 2b. Use other virtualization software. This Video describes a method to get classic civ 2 to work using free (open source) software. There is an updated video. If you have other methods, or want to describe these methods in more detail, feel free to reply. However, please direct actual tech support questions to other threads so that this one remains easy to read.
