Thanks everyone for the patching info. I have just successfully upgraded my Civ3 v1.07f to v1.29f. For the record, and for the benefit of anyone new to patching, here is what I did:
1. I installed Civ3 v1.07f from the CD.
2. I downloaded the v1.29f patch (above), which is an exe file. I then ran the exe file.
3. I then tried to run Civ3, and encountered the dread 'load the CD-ROM' message, which abruptly terminated the game.
4. So I went to the link provided by Sacred57 (thanks!), downloaded and unzipped two files, and copied them into my Civ3 folder (C:\Program Files\Civ3). Since one of the files is named Civilization3.exe, this replaced the original file. Despite the fact that the orginal file was substantially bigger than the new file, everything seems to work OK.
Thanks again, everyone! :goodjob:
