Download & Installation
Before installation, quit Lightroom. After installation, Lightroom should load LrControl automatically. But sometimes it does not. To load the plug-in, open the plug-in manager from the file menu and click the Add button.
Mac Install Location
On the Mac the plug-in is installed for all users. Find the plug-in starting from the root folder of the system disk.
Windows Install Location
Due to a recent Windows SmartScreen change, Windows could block the installer and show you a warning. The installer is signed and safe to use, please choose more info and then install anyway. This problem will be fixed soon, an expensive extended validation certificate is needed to prevent this warning, it takes some time to save up for that.
Please use the default install location in the installer. Otherwise Lightroom will not load the plug-in automatically.
The plug-in is installed for the current user only.
Note that the AppData folder is a hidden folder.
These videos show how to load the plug-in form the plug-in manager.
Connect the controller before starting Lightroom. Once the plug-in is loaded, it will start receiving inputs from the controller automatically.
You can find the menu items for LrControl in the Lightroom Help Menu, under the Plug-in Extras submenu.
Control Functions Reference
LrControl can generate a printable web-page with all the control functions, including any changes you made. This page opens in your default browser and can be generated and viewed off-line.
