WIzardy's exe version number shows up on main menu screen when you start the game.
it does not matter whether you use 1.24 exe (the one that gog and the other platform's release use both) or higher version.

Kaucukivnik666's mod requires dll injection, by default the files CFInjector.exe and CFAgent.dll
should be in games main InstallDir, if somewhere else you need to add the full path inside the quotes in the batch file.
You must start the mod via the batch file, usually also present in game folder and called start!.bat by default
at least in the somewhat putdated versions i worked on.

The batch file should contiain the lines
______
echo off
cls
CFInjextor.exe "[fileName]" "[fileName]"
pause
______


You may als need to either deactivate the cutscene videos, by moving the files in folder \}data}Flics}Intro to another directory
or add some .dll's that adds the graphics compatibility which m$ failed to integrate into its OS


Regarding compatibility of K's mod and other mods,
while conflicts may not necessarily lead to the game refusing to work,
they make changes on the same files, i would not recommend to merge them,
too much effort even if you know exactly wat to adjust.
