Sorry for the delay in responce, but construction cut my cable so I have had no access for a couple of days.
I assume it is looking for French language files and you do not have any installed, It could also be that it cannot recognise a particular accent character used in French that you have no support for. So I doubt that the 1.04 patch would install for you either, but anything is possible and Flori would know much more about the patch details than me.
I think you need to get that original install to function properly and without unknown string errors.
What is the exact error message it gives you?
Can you take a look at the registy entry and see what language is listed there for CK?
