CS 777 soundmod for Marketplace

I bought the cs 777-200 from the marketplace and installed the FTSIM+ sound mod and followed the instructions but it says to place the sounds into a folder called sounds but that does not appear where the instructions say it should. I was wondering if it’s a different setup if it comes from the marketplace and if it’s still possible to use the soundmod.

Same here I think that you have to have the version from cs

I believe I managed to get it to work using the CS improvement mod
