download/install

I'd love to try the SoW Napoleon mod but have no idea how to use 7zip. Also, the downloads from page 1 of this forum came in with Explorer icons, which I have never seen before. Any suggestions for the non-technical?

Welcome to the forum. 7zip is just another packing program. It does a little better job than zip. You can download the program here: 7 Zip Program Use it to unpack the 3 mod pieces.
As for the 2nd issue, I am not sure what you are seeing. Can you download the 7zip files?

When I click on the links you provided for download it appears the download is taking place but instead of a 7zip or other compressed file icon it comes through as an Explorer icon. I have 7zip installed.

I just realize DropBox is the app that appears when I go to download but I don't know how to change.

If you click on the name of the file, it will automatically download to your download folder. If that doesn't work, there will be a button in the top left of the webpage that will allow you to download the file.

Finally had the chance to come back to this and seem to have downloaded the 3 files to my desktop ok using 7-zip. But I'm used to automatic installers and have no idea how to install these properly. Any help would be appreciated.

They go in the Mods folder in the game directory.  If you have the game on Steam you can easily navigate to the directory by right clicking on the game, going to Manage -> Browse Local Files.  (If your game is not on steam then you will have to navigate your file browser to find the game directory.  Maybe someone else here can point you to where that directory may be if you're still struggling. Maybe in My Games->Scourge of War? I'm not sure where the non-steam version installs to.)  In there there will be a Mods folder.  You put the sprites, the map, and the mod folders right in there and when you launch the game you go into the game's mod manager and activate them.  Don't use the default mods that come with the game with KS Mod.

Thanks for the help. Did what you suggested, clicked KS mods and unclicked others, restarted game. All I see are the Waterloo scenario options. How do I access KS options? (FYI interested mostly in single player)

Further to last note, I have Waterloo version 1.03, so that's not the issue. Tried uninstalling/deleting all SoW files, reinstalling SoW Waterloo then re-extracting KS files to desktop and placed in mods folder again, selected KS mods only, restarted game, restarted computer: all to no avail. My only game options are stock Waterloo scenarios. Do I also need to purchase SoW Gettysburg and/or other Civil War version? What am I doing wrong?

You may have the "folder within a folder" problem. Go to your Mods folder and then to the KS Napoleon Mod II 133 folder. Is there another folder inside it with the same name, (KS Napoleon Mod II 133)? If so, move all the folders out of that 2nd instance, (i.e. Graphics, Layout, etc.) into the first KS Napoleon Mod II 133 folder. When the 2nd instance is empty, delete it. Do that for the other two pieces of the mod, Supplemental maps and KSSprites.

Worked, you're a genius. I'm sure I'll be back for more help though...

you're a genius
