A linux native installer for MPI packages (TTW, BSA Decompressors, so far only tested TTW and FNV/Oblivion Decompressor).

To run it all you need to do is either double click it and allow executing, or chmod +x mpi_installer_gui.

You can also download the the tool through Nexus if you prefer. https://www.nexusmods.com/site/mods/1657

If you want to support the things I put out, I do have a Ko-Fi I will never charge money for any of my content. Discord
