How do you perform a Fallout 4 downgrade? Patches and updates can sometimes make or break your gameplay experience, especially if you’re partial to mod playgrounds like Bethesda’s Fallout 4. The most innocuous change can have dire consequences for your favorite mods, and in some cases only a downgrade can get them working again.
Fallout London is one such mod. The popular passion project hit a roadblock following the surprise Fallout 4 next-gen update that caused a compatibility clash with many of the mod frameworks that power it. Thankfully, developer TeamFOLON has made it easier than ever to perform a Fallout 4 downgrade to roll back those changes. Given that Fallout 4 is one of the best PC games of all time, it stands to reason you own the Steam version. We’ve got a Fallout 4 mod to downgrade it on Valve’s platform, along with manual instructions if you want to downgrade Fallout 4 without installing Fallout London in the process.
How to downgrade Fallout 4 for Fallout London
The easiest way to downgrade Fallout 4 is by installing the official Fallout London Downgrader and Addons mod created by TeamFOLON. This mod includes the FOLON Downgrader program, which condenses the Fallout 4 downgrade process into a straightforward launcher installation.
It’s important to note that the above mod is tailored for the Steam version of Fallout 4. The GOG version of Fallout 4: Game of the Year Edition is “directly compatible with Fallout London” so players who own it on the DRM-free platform have fewer hoops to jump through. Simply install Fallout 4: GOTY Edition and Fallout London via GOG Galaxy, disable your cloud saves, and launch Fallout London.
Unfortunately, those who own Fallout 4 on Epic Games Store are out of luck, since the digital storefront doesn’t include an update rollback feature.

Fallout 4 downgrade no license error
If you’re trying to downgrade Fallout 4 the manual way, our instructions have been made specifically with the Fallout 4: Game of the Year edition in mind. Fallout London in particular needs all the DLC files to work, so if you’re missing any of the addons, just know that you’re going to have to purchase them if you want to proceed.
It’s also worth pointing out that downloading the depot files via Steam may take you some time. Steam’s console doesn’t make it clear, but the total file size is close to 90 GB, so it may take a while to redownload the entire game depending on the speed of your internet.
