If you want to get started with modding your game, let me know:
Which of the game are you modifying? (Forza Horizon 4 or 5?)
The original Horizon tool was a legendary piece of software for Xbox 360 modding. While it is largely obsolete for modern Forza Horizon titles (FH4 and FH5), many of its core concepts, like "rehash and resign" (repairing a save file's digital signature), are still the foundation of modern save editing.
"Invalid Profile" error after attempting to sync edited save. Steps to Reproduce: Extract original save from
Look in %LOCALAPPDATA%\Packages\Microsoft.624F8CC58A3_8wekyb3d8bbwe\SystemAppData\wgs\ (Folder names use randomized strings).
Beyond account bans, other risks include:
If you play 100% solo (Drivatars, no leaderboards, no convoys), a save editor harms no one. The moment you join a PvP race or sell a modded car on the Auction House, you are actively ruining the experience for honest players.
The result? You load the game to find a garage overflowing with rare cars like the Ferrari 250 GTO or the elusive Toyota Trueno AE86.
Disconnect your PC or console from the internet while loading modified data to prevent immediate cloud-sync bans.
