I ran into a crash with the nuclear bombs, as their file seems to be missing or bugged, it was related to wwII in the pacific.
The current file for "Light Tank" is missing, there is only the tank and main battle tank files, and the tank file is currently empty.
I try to answer both posts together, as they both are targeting to the same topic.
The
scenario search path in the Scenario Properties folder points to many conquests of C3C, too - among them the conquest WWII in the Pacific. Here is that path in RARR (it also exists in the versions of RAR including RAR 1.04 Betatest and triggered especially some problems with the link to the PTW Extras\units):
..\..\Civ3PTW\Extras\Medieval Japan\;..\..\Civ3PTW\Extras\World War II\;RARR;..\..\Conquests\Conquests\Napoleonic Europe;..\..\Conquests\Conquests\WWII in the Pacific;..\..\Conquests\Conquests\Middle Ages;..\..\Conquests\Conquests\Mesoamerica
1. Concerning the Light Tank:
Doc T. changed the graphics of the armor to the light tank graphics (as can be seen in his change log). This can be done easily be rewriting the pediaicons entry for the Armor to point to the Light Tank animations. This unit is included in the units folder of the Conquests\WWII in the Pacific.
It is not necessairy, that the unit folder of RARR contains the Light Tank unit. It is enough, when the unit is in the units folder Conquests\WWII in the Pacific. This requires, that the Conquests\WWII in the Pacific are installed properly at the correct place. If you have problems here, of course you can also copy that unit from the Conquests\WWII in the Pacific units-folder into the RARR units-folder, as the RARR-folder is also included in the search path.
As this all could be too complicated for some civers, I will include another version of the Light tank directly in The RARR units folder with the next update of the mainfile - but this wouldn´t come too quick. Wyrmshadow made some units that are better than the Firaxis Light tank.
2. The same problem is with the nuclear bomb. It needs the files of the Conquests\WWII in the Pacific units-folder.
But here another additional problem occurs:
Until now, the correct settings for nuclear units and their blast and smoke and waste-animations, combined with the trembling of the complete screen are a riddle even for the best graphical experts in these forums. They work different than normal graphical settings, as they are a special addition of different components of graphics. Even if trying to transport the original nuclear bomb unit directly into a C3C scenario (and even if setting it to the different speed of unit animations that is used for that unit), only causes to see the the last parts of smoke of the explosion, the fallout and to hear the sound - no blast and no trembling of the screen. I have even seen nuclear missiles of prominent graphics-specialist, that were flying backwards before exploding.
Wyrmshadow made some graphics of nuclear explosions with less images. Here at least some parts of the blast can be seen.
So whenever possible for nuclear bombs dropped by planes I still link to the Conquests\WWII in the Pacific unit to have the full effect of the nuclear weapon on the screen.
Both situations that are reported are not errors, but there is no access to the proper conquests files.

I also gave you a welcome at CivForum.de when I got aware of your post, but at CFC the orchestra is bigger.
