I downloaded all the files and installed each of them into separate folders. so the first file i put (for name's sake) into Chiv2, then the patch into a new folder Chiv2.3 and finally the hot fix into a new folder called chiv2hotfix.
This is very important however, within your med 2 folder, make a backup of the data folder, when I did it, it made a folder called data - copy... as long as you have a copy of an unaltered data folder you should be OK.
Now, the next step. I copied and pasted the sicilian folder from the first installer into the mods folder, and copied the data folder from that said installer into the medieval 2 directory, it should ask if you want to overwrite. Say yes, remembering you made a back up of the original. Now, do the same with the next two folders in order of the patch and finally the hotfix.
Hopefully you have used the kingdoms launcher app. which can be found here.

Download the file first, obviously. Once done run it. In the top right click on file, mouse down to new mod. In the mod name tab you can put whatever you want, so in this case we can put Chiv2. Down to the third tab, path, over on right is browse click that. That should bring you to your med2 folder, browse to mods and whichever mod you want, so in this case Sicilian Vespers and click ok. Underneath the path should be 2 options for game exe, use kingdoms. Now that is done.
Moving forwards and you have installed all the files in order, 3 - 3.3 - 3.3 hot fix, you should now have a "Chivalry II - The Sicilian Vespers 3.3" desktop icon, or within the Sicilian Vespers folder. Make sure it says
3.3. Choose your era, it gave me an error when finished but didn't seem to screw anything up. Now goto your med 2 kingdoms via steam, let the launcher start, click play and "Chiv2" should be an option now. If everything has been done properly, it should not crash upon campaign start now.
