Persistent "Failed to load il2cpp" Error on Startup

[Fulkann]

Problem Description: I am unable to launch the Pokémon Revolution Online client. Every time I try to run the executable, I receive the "Failed to load il2cpp" error message. I am using Windows 11 (64-bit).

What I have already tried:

• Visual C++: Installed the latest Visual C++ Redistributable packages  x64.

• Antivirus/Firewall: Added the entire game folder to Windows Defender exclusions. Checked protection history, and no files were quarantined or deleted.

• File Integrity: Re-downloaded and re-extracted the game files multiple times. Verified that GameAssembly.dll is present in the folder.

• Permissions: Ran the game as an Administrator.

• File Path: Moved the game folder directly to C:\ to ensure there are no special characters or long paths.

• Compatibility: Tried running in compatibility mode and disabling full-screen optimizations.

Despite these steps, the error persists. Any help would be greatly appreciated.

Hello @Fulkann,

 

Thank you for the additional screenshots and information.

The client files appear to be extracted correctly, including the il2cpp_data folder, so this does not seem to be an extraction issue.

This type of error is commonly related to antivirus/security software or missing system dependencies blocking the client from loading correctly.

Please try the following:

• Reinstall both the x64 and x86 Microsoft Visual C++ Redistributables.
• Make sure your Windows installation is fully updated.
• Temporarily disable your antivirus/firewall and test the client again.
• Ensure the game folder is added to your antivirus exclusions.
• Redownload the client and extract it again using a program such as 7-Zip or WinRAR.
• Run the client as Administrator.

If the issue still persists afterward, please let us know.

Looking forward to your reply.
