It is highly recommended to install Skyrim SE and all modding tools outside of the default folders, C:\Program Files and C:\Program Files x86. This is due to permission issues with the OS that may occur at some point later on and potentially break certain mods or tools. Better to not install anything there in the first place.

Additionally, it is important for your Skyrim Special Edition folder and Mod Organizer 2 to be on the same drivepreferably on an SSD which will improve performance over an HDD (eliminating stutters and drastically decreasing loading screen times).

Please note: Skyrim SE by itself has a size of almost 13GB. A decent mod setup can reach 50-100GB quite easily (depending on the type of mods you install). The current versions of The Phoenix Flavour takes up around 50GB of space.

1.1.1 Uninstall Skyrim SE

Obviously skip this step if you don’t have SSE installed.

  • Open Steam and go to your Library.
  • Find The Elder Scrolls V: Skyrim Special Edition in the list, right-click and select Uninstall.
  • Wait for the process to complete before you continue.

1.1.2 Create a new Steam Library

In order to keep your SSE installation outside the default folders, you will probably need to create a new Steam library. If you already have a Steam library on your chosen drive, there are instructions here on how to add a second library on the same partition.

  • Launch Steam and open the Settings.
  • In the Downloads tab, select Steam Library Folders.
  • Click Add Library Folder.
  • Point it to a location somewhere outside your C:\Program Files and C:\Program Files x86 folders on the hard drive where you wish to install Skyrim SE and Mod Organizer 2.
    • Again, if possible this should be your SSD.
    • My personal Steam library (for SSE and FO4) is under C:/Modding.
  • Close all windows when you are done.

1.1.3 Reinstall Skyrim SE

  • Launch Steam and open your Library.
  • Go to Skyrim Special Edition and click install.
  • As location, select the Library you just created.


For the purposes of this guide you must run a specific version of Skyrim SE. That is typically the latest version unless there recently was an update and the guide is still running on the previous version in which case you need to roll back.

The current supported version of Skyrim SE is:

If you updated to a newer version, please refer to this guide here in order to roll back.

1.2.1 Instructions

  • Navigate to your root folder.
  • Right-click SkyrimSE.exe and select Properties.
  • Switch to the Details tab and check under Product version.


Should Skyrim SE receive another update – which is not unlikely because of the Creation Club, unfortunately – SKSE64 and all dependent mods will need to be updated as well. This will probably take a few weeks.

However, you can continue playing the previous version with SKSE64 and all your mods by simply setting Skyrim SE to only update when launching the game – since you start the game through the SKSE64 launcher, Steam will never update.

1.3.1 Instructions

  • Find The Elder Scrolls V: Skyrim Special Edition in your Steam Library.
  • Right-click it and select Properties.
  • Switch to the Updates tab.
  • Under Automatic updates, make sure it is set as Only update this game when I launch it.
  • Problem solved!
