Update on version...says Game of the year on box....in fine print Civ4:Warloads. I do not have Beyond the Sword version.
That explains everything!
There are two expansions for CIV, in addition to the original game. It appears that you only have the original game and the first expansion, if your game includes the original. The expansion won't run without the original game.
The 3.19 patch is for the second expansion, "Beyond the Sword" (usually referred to as BTS). So, when you run the patch it is looking for files to update that are not there, which is why nothing happens.
Only BTS has the disc free patch. All BTS patches before 3.19 still require the disc to be in the drive. Both the original game and the first expansion (Warlords) require the disc to be in the drive. Microsoft has removed the code (secdrv) from Windows 10 which allows it to access the CIV discs (as well as many other games) because they had written in a way that allowed hackers to find a way into the system, so Microsoft removed it as a security risk.
So, if you want to play CIV on Windows 10, you will need to be sure that you have the original game in the package with Warlords and then buy BTS (or get someone to gift it to you) and then run the patch, if your BTS is not already 3.19. Alternatively, you can purchase an online DRM download version of CIV, which will not require any discs. There are several online sources. If you ask in a thread in the General Discussion forum, people there will tell you where they got it and what they think of the service. Each of the various download versions only work with the expansions from the same service. If you want to be able to use the disc version that you have, you will need a disc version of BTS. A download version won't work with your disc.
