What did you use to convert the Steam version? It has to be converted to work.
The disc problem is because you don't have a HDD, Flash Drive, or Virtual Drive labeled FF7DISC1. You can rename any drive to FF7DISC1, or you can mount this blank ISO to a Virtual Drive using Daemon Tools Lite. You must have a drive labeled FF7DISC1 before you use a game converter, and keep it labeled that afterwards when launching the game.
Which version of my textures are you using? To get them working in [game_dir]\mods\mod\battle|world, you need to have the PNG versions. The LGP versions are for manually importing them into battle.lgp and world_us.lgp, and the IRO version is for use with 7th Heaven.
I finally decided to follow step by step instructions of this mod
