My plugins are appearing in After Effects, but not Premiere

Before following these steps, ensure that:

• The plugins you're looking for are compatible with both Premiere & After Effects.
• You have a GPU that's got at least 4GB of VRAM per monitor

Once both of those have been accounted for, you can follow either of these two sets of steps:

Option 1:

1. Close Premiere & After Effects.
2. Temporarily move all of the files out of Adobe's MediaCore folder (ex. to your desktop):
   • For Windows: C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore\
   • On Mac: /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore/
     • You can copy/paste that file path into the Go > Go to Folder... menu of Finder
3. Re-launch Premiere while holding "Control+Shift (Windows) or "Command+Shift" (Mac OS)
    until the Adobe splash screen disappears
4. Close Premiere
5. Put one of the folders/files of whichever plugin wasn't appearing in Premiere back into the MediaCore folder
6. Re-launch Premiere and check that the plugin is present
7. Close Premiere, and move other plugin files to move back into the MediaCore folder
8. Re-launch Premiere
9. Repeat until all plugins load

Option 2 (Windows only)

If Option 1 failed or didn't affect anything, try following these steps:

1. Close Premiere & After Effects
2. Head into the Start menu, search for regedit and launch it to open the Registry Editor
   • As a precautionary measure, feel free to backup your Registry by selecting File > Export and save all of the Registry to someplace accessible
3. Within the Registry Editor, head to HKEY_CURRENT_USER\Software\Adobe\Premiere Pro\7.0\PluginCache.64\en_US
   • The "7.0" in the file path may differ on your setup; the steps are the same regardless
   • For example, the location for Premiere CC 2017 is HKEY_CURRENT_USER\Software\Adobe\Premiere Pro\11.0\PluginCache.64\en_US
4. Here you'll see folders showing plugins on the left, and when they're clicked, you'll see a few columns with Name, Type, and Data set
5. Click the plugins on the left and, on the right, you'll see a section labeled Ignore
6. For each plugin, if Ignore is set to 1, set it to 0
7. After that's done, close the Registry Editor and relaunch Premiere
