Reaper – Plugin Not Showing Up (PC)

Problem: You installed Safari Plugins but they don’t appear in Reaper.

---

Step 1: Open Reaper Plugin Manager

Open Reaper → Options → Preferences → Plug-ins → VST.
This window will display all currently scanned plugin directories and detected plugins.

---

Step 2: Verify Plugin Paths

Make sure the folder where Safari Plugins installed is included in the VST plugin paths:

C:\Program Files\Common Files\VST3\

If the folder isn’t listed, click Add… and select it.

---

Step 3: Rescan Plugins

In the VST preferences window:

1. Click Clear cache/re-scan

2. Enable:

   • Rescan previously failed plugins

   • Scan for new plugins on startup

3. Click OK to start a full rescan.

Check the FX browser; Safari Plugins should appear.

---

Step 4: Clear VST Cache (Windows, VST2 & VST3)

If the plugin still doesn’t appear:

1. Click Options → Show REAPER resource path in Explorer

2. Close REAPER

3. Manually delete the file:

reaper-vstplugins64.ini

4. Reopen REAPER. It will rebuild the plugin cache and rescan all VST3 plugins.

---

Step 5: Verify Installation

Open File Explorer and navigate to:

C:\Program Files\Common Files\VST3\

Confirm that the plugin files exist (.vst3).
If missing, reinstall Safari Plugins using the Windows installer.

---

Step 6: Restart Reaper

Close and reopen Reaper to refresh the plugin list.
Search in the FX browser to confirm Safari Plugins are available.

Tips / Troubleshooting

• Only VST3 format is required.

• Keep only the latest plugin version to avoid conflicts.

• If a plugin was previously blocked or failed to load, clearing the cache and rescanning usually resolves it.

• Make sure Reaper has permission to access Program Files if installed system-wide.
