2. Disable Automatic Game Updates

In EA App: Go to Settings > Downloads > Turn off "Automatic Game Updates". If FIFA 18 updates again, the encryption key will break once more.

Does This Work With EA App?

Yes. This was the biggest test. EA recently forced the shutdown of Origin, migrating everyone to the EA App. The old encryption key error got worse after the migration.

The new fixed version includes a "EA App Compatibility Mode" toggle inside the Tools menu. Turn it on, and the mod manager injects the key during the game’s pre-launch handshake. It works flawlessly on Windows 10 and Windows 11 (23H2/24H2). EA App Migration: The forced move from Origin

Part 5: Why "Encryption Key Fixed" Is Still a Trending Search

As of late 2025, the search term "fifa 18 frosty mod manager encryption key fixed" continues to trend for three reasons:

  1. EA App Migration: The forced move from Origin to the EA App broke many older key injection methods. New fixes emerge weekly.
  2. FIFA 18 Modding Renaissance: With newer FIFA titles (FC 24, FC 25) being nearly unmoddable, players are returning to FIFA 18 for full conversion mods (e.g., FIFA Infinity’s FIFA 18 to 2025 Season Patch).
  3. False YouTube Tutorials: Many creators repost old, non-functional fixes, driving frustrated users to search for a "real" fix.

Step 2: Editing the ModManager.cfg File (The "Hard" Fix)

If Step 1 didn't work, or if the profile isn't showing up, you can manually inject the encryption key into the configuration file.

Note: FIFA 18 actually does not use a unique encryption key (it uses default encryption), but the Manager needs the entry to exist.

  1. Close Frosty Mod Manager completely.
  2. Go to your Frosty Mod Manager installation folder.
  3. Open the file named ModManager.cfg using Notepad (Right-click > Open With > Notepad).
  4. Look for a section that looks like <GameProfiles>.
  5. You need to paste the following code block inside that section. If other games are there, just paste this alongside them:
<GameProfile>
    <Id>FIFA18</Id>
    <Name>FIFA 18</Name>
    <DisplayName>FIFA 18</DisplayName>
    <ExecutableName>FIFA18.exe</ExecutableName>
    <EncryptionKey></EncryptionKey>
    <RequiresEncryptionKey>True</RequiresEncryptionKey>
</GameProfile>

(Note: The EncryptionKey field is intentionally left blank because FIFA 18 uses the default key logic, but setting RequiresEncryptionKey to True tells the Manager to apply its standard FIFA decryption logic).

  1. Save the file and close Notepad.
  2. Re-open Frosty Mod Manager.
