Installing Patches (Non-English)
The 1.03 - 1.05 patches are done in English only. The patches can be applied to installs in other languages but doing so will convert the game to English.
Change to English
If you selected another language when you originally installed the game you must do the following to be able to install the patches.
Step 1: Rename the Language folder under Warlords IV to English. For example if you have a French folder rename that to English.
Step 2: Install the patch.
Step 1: Rename the English folder back to the original Language folder.
The game is now patched and can be run.
French Translation
A warlord named Vifarc translated the 1.05 patch into French. So if you originally installed in French you can go back to using French after installing the 1.05 patch.
Step 1: Download the French Translation for 1.05 from the downloads section.
Step 2: Extract the archive into the Language folder. Just make sure to extract over top of the existing XML files. You'll know you got the location correct if you are asked to overwrite the existing files. Say 'yes to all'.
The game is now back to French.
NOTE: If you would like to translate 1.05 into another language it's a very straight forward and quick process. It involves adding new text strings for the additional content in the 1.03-1.05 patches. Somewhere around 30-50 lines of in game text plus updating the help files.
