How Do I Downgrade Skyrim?

If your Skyrim is up to date, you will NOT be able to install some modpacks until you downgrade Skyrim.

This file contains instructions on how to downgrade to Version 1.6.1170 of Skyrim.

Open a command window “Run” by pressing «Win + R» and then enter the command: steam://open/console, and then press Enter. This will open the console tab in Steam.
At the bottom there will be a space for you to enter the code. Enter these codes one at a time - paste only the first line, press Enter, and wait for the console to show that the download is complete before pasting the next one.

Do NOT paste all three commands at once. Entering the next download_depot command before the previous one finishes will cause the download to fail or leave you with missing/corrupt files.

Check each depot has downloaded successfully. It will download the files to the “steamapps\content\app_489830" folder in your main/primary Steam install folder (this is always where Steam downloads depots to via console commands, even if Skyrim itself is installed in a different library). If you cannot find it, just search your primary Steam folder for “depot 489831”, “depot 489832”, and “depot 489833” after the download is done. If you are missing files, simply redo the depot command until you have all the files. DO NOT SKIP THIS CHECKING STEP

depot 489831 should contain 16 files

depot 489832 should contain 26 files

depot 489833 should just contain Skyrim’s exe
Replace your “steamapps\common\Skyrim Special Edition” files with the ones in “depot 489831”, “depot 489832”, and “depot 489833”, in that order. Copy the contents and paste them into your Steam installation folder, overwriting files which are already there (do not copy the depot folders themselves - just their contents).

Once you have downgraded, restart Wabbajack. Enter the same install criteria as you did the first time.

Do not under any circumstances use Halgari’s download patcher as it currently doesn’t work on downgrading to 1.6.1170.
