'Failed to load il2cpp' while opening the client

[Sayanesh]

I have checked Windows Threat protection, It is quarantining the file "GameAssemblly.dll and its also saying that its a trojan file. Its is happening after the recent update (not only for me). I'm worried if this is a actual threat, can u please look into it ?

Also, when I tried to redownload the client, my Windows Defender showed this threat.

Good day @Sayanesh

 

I apologies for the inconvenience. 

 

At the moment, when some players attempt to update their client, Windows Defender labels one or two of the files as a Trojan virus. This is because some of PROs files are encrypted, which can trigger a false-positive. Windows Defender will then quarantine the file to protect your computer. Some players might get a pop up saying "Failed to load il2cpp", others have an issue when the patcher is extracting the files.

 

There are a couple methods to bypass this issue:

1) In windows security, click on the "Virus & threat protection". Here you can click on "protection history", which will show the threat that was quarantined. Clicking on it will probably bring up a Windows Security permission. Once accepted, you can click actions to restore. This restores the file, allowing the game to access it. 

 

Sometimes this doesn't solve the problem though. Now we'll apply an exception to your anti-virus, which is will force it to ignore files in a certain location. I would recommend removing your PRO files from your PRO folder.

 

2) In windows security, click on the "Virus & threat protection".  Under "Virus & threat protection settings", click "Manage settings". Scroll down to the section for "Exclusions", and then click "Add or remove exclusions". After accepting the Windows Security request, you can click "+ Add an exclusion". You will then pick the folder that will contain your PRO game files. Now Windows Defender will ignore this folder when looking for security threats.

 

At this point, I would recommend emptying your trash and performing a reboot. Next, download a fresh install of the PRO client (direct download from the PRO website), and place the files in your exclusion folder. You can now launch the game from this folder, and it should bypass the security restrictions and allow you to play PRO. 

 

I hope this information finds you well and gets you back in game.

Thanks for the detailed explanation and the suggested workaround!

That said, excluding the game folder or restoring quarantined files manually doesn’t seem like a great long-term solution — the game really shouldn’t be triggering antivirus alerts in the first place. It’s not ideal to have to lower security settings just to get it running, especially if the files are legitimate and properly signed.

Are you currently working on a proper fix for this false-positive issue? And if so, do you have an approximate timeframe for when it might be resolved?

Good day @Chandrianos

 

Per one of the developers, " I always upload the files to the most popular antivirus programs, and after some time, they stop getting flagged. The issue is worse right now because I had to release new clients. Normally, I build, upload the files, and release them later, but that process doesn't work as smoothly when I can to upload hotfixes....it should settle down once the file stops getting flagged, which usually takes about one to two days. Its often faster, but we have absolutely no control over that."
