Updating Frosty Mod Manager involves checking your installed version, downloading the latest official package, and setting it up in a separate folder. Frosty does not use a traditional automatic update system.

Keeping Frosty Mod Manager up to date ensures better compatibility with supported games, improved stability, and access to the latest features and bug fixes. Updating the software is usually a simple process, but it’s important to back up your existing configuration and mods before installing a newer version to avoid compatibility issues.

This guide explains how to update Frosty Mod Manager safely step by step, including downloading the latest release, preserving your settings, updating installed mods if needed, and troubleshooting common update problems. By following these steps, you can upgrade Frosty Mod Manager without losing your mod setup or affecting your game installation.

Check Your Current Frosty Version

Checking the installed version helps you determine whether an update is available. It also prevents you from downloading the same release again.

Carefully compare the version number with the latest release listed on the official Frosty Toolsuite GitHub page.

Find the Installed Version Number

Open Frosty Mod Manager and check the title bar, About section, or program information window. The installed version number should appear in one of these locations.

You can also right-click FrostyModManager.exe, open Properties, and check the Details tab. Write down the complete version number before continuing.

Compare It with the Latest Release

As of July 13, 2026, the official CadeEvs GitHub Releases page still lists Frosty Toolsuite 1.0.6.3, released on September 29, 2023, as the latest complete public release.

A newer Frosty Toolsuite rewrite is under development using .NET 8, but the official repository describes it as an early-development project without a functional user interface. It is not yet a replacement for the stable Mod Manager.

Your Frosty installation is up to date if it already shows version 1.0.6.3. Download an update only when the official release page lists a newer stable version.

Back Up Your Existing Frosty Setup

Before updating Frosty Mod Manager, create a backup of your current setup. This protects your mod lists, profiles, plugins, and configuration files if the updated version does not work as expected.

Store the backup in a separate folder outside the main Frosty directory. Give the folder a clear name that includes the current version or backup date.

Save Applied Mod Lists

Open each game profile and review the mods currently listed in the applied mods panel. Save the mod pack through the available export option when your Frosty version supports it.

You can also take screenshots of the applied mods and their load order. This provides a simple reference if you need to rebuild the setup manually.

Make sure the backup records:

1. The names of all active mods.
2. The order in which the mods are arranged.
3. Required dependencies and add-ons.
4. Any disabled mods you may use later.

Copy Important Profiles and Configuration Files

Close Frosty Mod Manager before copying its files. This prevents incomplete or damaged configuration data.

Copy the folders and files connected with game profiles, plugins, settings, and saved mod packs. Keep the original folder structure so the files are easier to restore after the update.

Do not delete the old Frosty installation immediately. Keep it until the new version opens correctly, detects the game, and loads your existing mods.

Download the New Updated Frosty Mod Manager

As of July 13, 2026, the official GitHub release page lists Frosty Toolsuite 1.0.6.3 as the latest stable public version. This release was published on September 29, 2023, and is marked as the latest complete release.

A newer Frosty Toolsuite rewrite is under development, but the official project states that it does not yet have a public release or functional user interface. It continues to direct regular users to version 1.0.6.3 for stable use.

Follow these steps to download the correct version:

1. Open the official CadeEvs FrostyToolsuite Releases page on GitHub.
2. Select Frosty Toolsuite 1.0.6.3 marked as the latest release.
3. Open the Assets section under the release.
4. Select the Frosty Mod Manager package rather than the Editor or source-code package.
5. Save the downloaded ZIP file in a separate folder.
6. Scan the file with Windows Security before extracting it.

Do not overwrite your current Frosty folder with the downloaded files. Extract the updated package into a new folder so the existing version, mods, and settings remain available if you need to restore them.

Select the Correct Mod Manager Package

Open the Assets section of the official Frosty release page and choose FrostyModManager.zip. This package is intended for users who want to install, organize, and launch mods.

Do not select FrostyEditor.zip unless you plan to create or edit mods. The source-code archives are intended for developers and are not required for normal mod management.

Before downloading, confirm these details:

1. The file name is FrostyModManager.zip.
2. The package belongs to the correct official release.
3. The file is downloaded from the official GitHub repository.
4. The ZIP file is scanned before extraction.
5. The package is saved separately from the old Frosty folder.

Choosing the correct package prevents users from downloading unnecessary development files or the wrong Frosty tool.

Extract the Updated Frosty Files

After downloading the new package, extract it into a separate folder. Do not copy the files directly over the existing Frosty installation, as this may create conflicts between the old and new program files.

Create a clearly named folder, such as Frosty Mod Manager New Version, and extract the complete ZIP archive into it. Keep all files and subfolders together, as Frosty may depend on the included libraries and plugins.

Follow these steps:

1. Right-click the downloaded ZIP file.
2. Select Extract All.
3. Choose a new and empty destination folder.
4. Wait for every file to finish extracting.
5. Open the folder and locate FrostyModManager.exe.
6. Keep the old Frosty folder until the updated version has been tested.

Do not run Frosty directly from the compressed ZIP file. A complete extraction helps prevent missing-file errors, plugin problems, and startup failures.

Create a Separate Folder for the New Version

Create a new folder before extracting the updated Frosty files. This keeps the new version separate from the current installation, making testing safer.

Use a clear folder name that includes the version number, such as Frosty Mod Manager 1.0.6.3. Store it in an easy-to-find location, such as Documents or a dedicated modding folder.

Follow these steps:

1. Open the location where you want to store Frosty.
2. Create a new empty folder.
3. Add the version number to the folder name.
4. Extract the complete ZIP package into this folder.
5. Keep all files and subfolders together.

A separate folder also makes it easier to return to the old version if the updated setup causes errors.

Avoid Overwriting the Existing Frosty Folder

Do not extract the new files directly over the old Frosty installation. Mixing files from different versions can cause missing libraries, broken plugins, startup errors, or profile problems.

Keep the current Frosty folder unchanged until the new version opens correctly and detects your game. Test one game profile and one mod before moving additional files.

You should only remove the old folder after confirming that:

1. The updated version starts without errors.
2. The correct game profile appears.
3. Existing mods can be imported or restored.
4. Plugins and settings work correctly.
5. The game launches successfully through Frosty.

Transfer Your Existing Mods

After extracting the updated Frosty version, carefully transfer your existing mods. Moving the files in an organized way helps preserve your previous setup and reduces the risk of missing or broken mods.

Do not delete the old Frosty folder until all mods have been restored and tested. Keep the backup available in case a file or mod pack needs to be imported again.

Restore Saved Mod Files

Locate the folder where your original mod files were stored. Copy the saved mod packages into a separate folder that is easy to access from the new Frosty installation.

Follow these steps:

1. Open your old mod storage or backup folder.
2. Copy the saved .fbmod files and related archives.
3. Place them in a new mod backup folder.
4. Open the updated Frosty Mod Manager.
5. Import the mod files into the correct game profile.
6. Check that each mod appears in the list of available mods.

Avoid copying unknown configuration files directly into the new Frosty folder unless you know they are compatible with the updated version.

Import Saved Mod Packs

If you exported a mod pack from the previous Frosty setup, use the import option in the updated version to restore it. This can save time by rebuilding the applied mods list and load order.

After importing the mod pack, review every mod carefully. Confirm that all required dependencies, add-ons, and compatibility patches are included.

Test the restored mod pack with one game profile before importing additional packs. If a mod is missing or outdated, import it manually or replace it with a compatible version.

Reconnect Frosty with Your Game

The updated Frosty Mod Manager may not automatically detect the game profile from the older installation. You may need to reconnect the program to the correct game executable before restoring or testing mods.

Make sure the game is fully installed and has been opened normally at least once. Close the game before creating the new Frosty profile.

Select the Main Game Executable

Open the updated Frosty Mod Manager and choose New or Scan for Games. Browse to the game installation folder and locate its main executable file.

Follow these steps:

1. Open the launcher used to install the game.
2. Find the game in your library.
3. Choose Browse Local Files or a similar option.
4. Return to Frosty Mod Manager.
5. Select the main file that ends with .exe.
6. Wait while Frosty creates the game profile.

Avoid selecting launcher, setup, repair, or update files. The correct executable usually contains the game name.

Confirm the Correct Game Profile

After selecting the executable, check that Frosty displays the correct game title and profile image. Also confirm that the installation path points to the active game folder.

Before restoring mods, verify these details:

1. The game name is correct.
2. The executable path matches the installed game.
3. The selected profile opens without errors.
4. The available and applied mod panels appear correctly.
5. Frosty can launch the unmodded game.

Testing the profile before adding mods helps separate game-path problems from mod compatibility issues.

Update the Game SDK Profile

A game update can change the files that Frosty uses to understand the game structure. When this happens, Frosty may display an outdated SDK profile warning or fail to open the existing game profile.

Updating the SDK profile allows Frosty to scan the latest game files and rebuild the information required for mod loading. The exact process can vary by game and Frosty profile, so users should follow the message displayed by the manager.

Fix the Outdated SDK Warning

Close the game and remove recently applied mods before starting the SDK update. Open Frosty Mod Manager as an administrator and select the affected game profile.

Follow these basic steps:

1. Read the warning message carefully.
2. Confirm that the game is fully updated.
3. Launch the game normally without mods when Frosty requests it.
4. Allow the game to reach the main menu.
5. Return to Frosty and continue the profile update.
6. Restart Frosty after the process finishes.

Do not use an SDK profile created for another game version. An incorrect or incomplete profile may cause loading errors or prevent mods from working.

Rebuild the SDK After a Game Update

Rebuild the SDK when Frosty reports that the existing profile is outdated after an official game patch. Keep a backup of your mods and profile settings before beginning.

After rebuilding, open the game profile and apply one compatible mod for testing. Launch the game through Frosty and check whether the mod appears correctly.

If rebuilding fails, repair the game files through the launcher and try again with an unmodified installation. Some games may require an updated Frosty profile to work with a newly patched version.

Test the Updated Frosty Mod Manager

After reconnecting the game and restoring your files, test the updated Frosty Mod Manager before applying your full mod setup. A simple test helps confirm that the new version can open the game profile, apply mods, and launch the game correctly.

Use only one trusted and compatible mod during the first test. This makes it easier to identify whether a problem comes from Frosty, the game profile, or the selected mod.

Apply One Mod for Testing

Choose a small mod that worked correctly in your previous Frosty setup. Avoid testing several mods at once, as conflicts can make the results difficult to interpret.

Follow these steps:

1. Open the correct game profile.
2. Import one compatible mod.
3. Move it to the applied mods list.
4. Confirm that it is enabled.
5. Check that no unnecessary plugins or mods are active.
6. Review the load order before launching the game.

A simple visual or interface mod is often suitable for testing because its changes are easy to identify.

Launch the Game and Check the Changes

Click Launch or Launch Game from Frosty Mod Manager. Wait while Frosty prepares the modified files and opens the required game launcher.

When the game starts, check the area affected by the test mod. Confirm that the expected visual, menu, character, or gameplay change appears correctly.

Also check that:

1. The game reaches the main menu without crashing.
2. The selected mod appears in the game.
3. No missing textures or error messages appear.
4. The game remains stable during basic testing.
5. Frosty opens the same profile correctly after restarting.

If the test is successful, restore and gradually apply the remaining mods. Test them in small groups so any compatibility problems can be identified more easily.

Common Frosty Update Problems and Fixes

Updating Frosty Mod Manager can sometimes cause missing mods, broken profiles, or game launch errors. These problems usually occur when files are moved incorrectly, the wrong game executable is selected, or older mods are incompatible with the updated setup.

Check each problem separately before reinstalling Frosty. Keeping the old version and backup files available makes troubleshooting easier.

Existing Mods Are Missing

Problem: The updated Frosty version opens correctly, but previously imported or applied mods do not appear.

Fix: Open the correct game profile and reimport the saved mod files. If you created a mod pack backup, use the available import option to restore it.

Follow these steps:

1. Confirm that the correct game profile is open.
2. Locate the folder containing the saved mod files.
3. Import the missing mods into Frosty.
4. Move them into the applied mods list.
5. Restore the original load order.
6. Check that all required dependencies are active.

Do not delete the old Frosty folder until every important mod has been restored successfully.

Frosty cannot open the Game Profile

Problem: Frosty may display an error when opening the profile or fail to recognize the connected game.

Fix: Remove the broken profile and reconnect Frosty to the main game executable. Make sure the selected file belongs to the current game installation.

Check the following points:

1. The game is fully installed and updated.
2. The correct main executable file is selected.
3. Frosty is running as an administrator.
4. The game folder has not been moved.
5. The SDK profile is not outdated.
6. Required Frosty files are present in the program folder.

If the profile still fails, repair the game files through the launcher and create the profile again.

Game Does Not Launch After Updating

Problem: Frosty opens normally, but the game does not start when the launch button is clicked.

Fix: Test the updated setup without mods first. A plugin, an outdated mod, an incorrect launcher setting, or a permission issue may be blocking the game.

Follow these troubleshooting steps:

1. Run Frosty Mod Manager as an administrator.
2. Open the EA App, Steam, or Epic Games launcher.
3. Disable all applied mods.
4. Launch the game through Frosty without modifications.
5. Repair the game files if it still fails.
6. Add one compatible mod and test again.

If the unmodded game launches correctly, gradually restore the remaining mods. This helps identify the outdated or conflicting file causing the problem.

Frequently Asked Questions About Updating Frosty Mod Manager

Updating Frosty Mod Manager is usually straightforward, but users may still have questions about versions, saved mods, profiles, and launcher settings. The answers below explain the most common concerns.

Conclusion

Updating Frosty Mod Manager requires more than replacing a few program files. Users should first check the installed version, confirm that a newer stable release is available, and create a backup of their existing setup.

The updated package should always be extracted into a separate folder. This protects the previous installation and makes it easier to restore mods, profiles, and configuration files if the new setup does not work correctly.

After reconnecting Frosty to the game, users should carefully restore their mods and test only one mod at first. The game profile, SDK data, launcher connection, and mod changes should all be checked before the full mod list is applied.

Keeping backups and testing changes gradually can reduce missing mods, profile errors, and launch problems. A careful update process helps maintain a stable Frosty setup and protects the work already completed in the previous version.
