(EDIT: don't forget that the ENB that you're wanting to use also requires the SE ENB Helper, so three pieces: basic framework (manual install), ENB Helper (mod manager install), and whatever version of Silent Horizons (manual install). Copy 'd3d11.dll' and 'd3dcompiler46e.dll' from the 'WrapperVersion' folder to the Skyrim SE installation folder. Just download the latest ENB version from the official website Once the download is complete, open 'enbseriesskyrimsevXXXX.zip' (where XXXX is the ENB version).

Once that is in place, the presets and such that you get from the nexus can be installed according to whatever instructions the mod author gives you. The installation of the ENB is very simple. (the versions at the bottom are linked to the appropriate page with a download button at the bottom of that page) If you haven't already installed the basic framework for SE, you can get it here: Other pieces can be packed up into an archive for use with your preferred mod manager inside the Data directory. Download recent ENB Binary here: ENB Skyrim SE Binary (click the binary icon) and extract 2. I didn't notice anything - only after installing the ENB. Some of those pieces need to be installed manually because they reside outside of the Data directory. Comp is only a few days old, but I did install Skyrim fresh on it last night and booted it up to play some to see if anything was off. There are several pieces that need to be in place for it to work. I don't use ENB on Skyrim (it's on my to-do list), but have started using it on FO4.
