Old Version Error

If you receive the following message:

You have been disconnected because you tried to connect with an old version. Application will now shut down. (code = 4002, -62)

then the game client is not in a valid state for the current server version.

As of now, there are 4 common causes for this problem:

• C++ 2015 (x86) is not installed
• d3dx9_43.dll is missing
• Windows Firewall, Defender, or antivirus deleted JFTSE.dll
• The game files are out of date

Fixes

1. C++ 2015 (x86) is not installed

If the required Microsoft Visual C++ runtime is missing, the client may fail to update or launch correctly.

Fix: Install the Visual C++ Redistributable (x86):

Download C++ 2015 x86 Redistributable

2. d3dx9_43.dll is missing

If the client cannot start because d3dx9_43.dll is missing, DirectX 9 components are not installed correctly.

Fix: Install the DirectX End-User Runtime:

Download DirectX End-User Runtime

3. Windows Firewall / Defender / Antivirus deleted JFTSE.dll

The anti-cheat file JFTSE.dll may be blocked, quarantined, or deleted by Windows Defender or third-party antivirus software.

Fix:

• Check your antivirus quarantine
• Restore JFTSE.dll if it was removed
• Add the game folder to your antivirus or Defender exclusions
• Make sure the anti-cheat files are not being blocked

4. Files are out of date

This is the most common cause of the old version error.

Fix: Always launch the game using:

FT_Launcher.exe

This will check for updates and download any missing or outdated files before starting the game.

Recommended Fix Order

If you get error 4002, -62, try the following in order:

1. Install the C++ 2015 (x86) Redistributable
2. Install the DirectX runtime
3. Check whether JFTSE.dll was deleted or quarantined
4. Run FT_Launcher.exe
5. Restart the PC and try again

Mac Users

Fantasy Tennis is a Windows game.

Mac users may be able to run the game through Parallels Desktop by installing Windows in a virtual machine. However, since JFTSE uses anti-cheat functionality, compatibility may vary depending on the setup. Parallels supports running Windows on Mac, but anti-cheat or low-level components can still be unreliable in virtualized environments.

Possible setup:

• Install Parallels Desktop
• Install Windows
• Install Fantasy Tennis / JFTSE inside Windows
• Run FT_Launcher.exe to update the client
• Start the game from the Windows environment

Notes

• Do not start outdated files directly if FT_Launcher.exe is available
• If the launcher does not repair the client, reinstall the game files and update again
• If security software keeps deleting files, create a permanent exclusion for the full game folder
