There is a number of ways to install a plugin in Capture One 12 once you have downloaded it.
- Double-click on the plugin.
- Open Preferences and select the Plugins tab. Click the + button in the bottom-left corner, then select the plugin in the file browser that pops up.
- Open Preferences and select the Plugins tab. Drag the plugin into the list of plugins.
Capture One 12 will then copy the plugin to the Plug-ins subfolder under Capture One and install it. The plugin should now show up in the list on the left of the Plugin manager tab and be ready to use.
