- YOU CAN CHANGE TO YOUR LANGUAGE EASILY BY RUNNING 'The Witcher 2\bin\Configurator.exe' AFTER INSTALLATION FROM CONVERTED SETUP (3XDVD5)
- This is not fully tested (partial tested on MULTI5 version) of the game, so write down if you have some isues.
- If you dont prefer 'C:\' as conversion and installation folder make sure that you change all letters from 'C:\' to letter of your choice ('D:\' or 'E:\', etc...) in the script file!
P.S
This is mine first conversion so don't mind if i missed out something
