Maybe, but I consider this installer finished as of the last bugfix. Unless something major changes (new version of Windows comes out that requires different compatibility settings, someone makes a new remixed/remastered soundtrack, ficedula releases a new version of the ff7music exe, a new bug is discovered), there won't be another release. I'm certainly not going to make another release just to automatically open ff7config and force them to change their audio settings.
edit: However, ff7config just changes a few things in the registry, nothing more. I might be able to have them set it within the installer without touching ff7config. I'll look into it.
