for starters, if you post a question like this below a map, nobody is ever gonna answer to you.
You should post questions like this in the forum.
If you are looking for patch 1.1 then you need to look in the appropriate section, which is under the download page, section CII patches http://cossacksworld.ucoz.co.uk/load/c_ii_patches/45
There you will find patch 1.1
But I'm not sure that is what you want because you say something like " but in need patch 1.0".
There is no patch 1.0. 1.0 is the game, the original vanilla game that came out. 1.1 is a patch to the game version 1.0
If for some reason the patch doesn't install, then it means you have the patch for a different language or you have a cracked version of the game.
And to be entirely complete: you don't need patch 1.1, you need patch 1.2. ALl the fixes from patch 1.1 are in patch 1.2,as it is a cumulative patch.
