Plug-in does not appear in Adobe Lightroom after installation
Why can I not find HDR Efex Pro 2 within Adobe Lightroom?
HDR Efex Pro 2 is located under File, then Export With Preset. If you do not see it listed, please make sure that Lightroom was available and installed prior to installing HDR Efex Pro 2. If Lightroom was not installed prior to installing HDR Efex Pro 2, please close Lightroom and run the installer again.
If Lightroom was installed prior to running the installer for HDR Efex Pro 2 and HDR Efex Pro 2 is not available, the Export settings within Lightroom may not be correctly enabled. In Lightroom, go to File, then Export. Next to "Export To," select Google. Then click the "Add" button under the Preset list, and title the Preset "HDR Efex Pro 2." HDR Efex Pro 2 will now be available under the Export With Preset menu.
