| Problem | Solution | |--------|----------| | “Failed to load Serum_s.dll” | Wrong bit version (32‑bit vs 64‑bit). FL Studio is 64‑bit – install 64‑bit Serum. | | Old version still opens | FL is caching. Go to → delete entry → rescan. | | Presets disappear | Your SerumPresets folder is elsewhere. Copy old folder to new install location (same as Serum.dll ). | | Splice says “up to date” but Serum says old | Splice version might lag. Download from Xfer if licensed. | | “License not found” after update | Re‑enter serial (Xfer users). Splice users: open Splice → “Repair” Serum. |

# Close FL # Run new installer as admin # Verify path: C:\Program Files\VstPlugins\Serum.dll # In FL: Plugin Manager -> find Serum -> unstar -> Scan and verify -> restar

The standard installer now includes Serum 2 , which is a free upgrade for all existing users. Option B: For Splice Rent-to-Own Users Open the Splice Desktop App. Go to the "Apps & Plugins" (or "Tools") section.
