Hello Peter! I am full of admiration for your scripts

Last time I was thinking how to make button in autorun which will be changing language.
Today I saw your Skyrim autorun and i said "damn, how did He do that?!" ;D
Tell me how did you do that if you can. I will be very happy if you give me your entire script. I am beginner in Inno Setup and that would be very helpful for me. Greetings

PS. Sorry for my English. I hope you could understand me.
