Hi, I dont think mod makers check this forum, but anyway, just a quick checklist. 1. Download latest Fluffy manager 2. Download the mod manually 3. Setup Fluffy to point to your RE2R 4. Just test whether you can launch the game (do the admin rights thing) 5. Place the RAR file into the following path Fluffy Manager > Games > RE2R > Mods > Your rar file 6. Optional: You may want to unzip the file , it should immediately show you 1 native folder/ 1 readme/1 screenshot (normally) 7.Activate mod. It should have some text "xx files are installed" 8. Run the game. Check the model viewer or run in game and swap costume.
