How to fix "An error occurred while starting Roblox" in Windows?

Issue: I am running Windows, and since a few days ago, I can't seem to be able to launch Roblox – I receive the “An error occurred while starting Roblox” message instead. Any tips on how to resolve this?

Solved Answer

Whether you're a long-time fan of Roblox or a newcomer excited to dive into the world of user-created online multiplayer experiences, encountering an error while trying to start the game can be frustrating. One common problem that Windows users often face is the “An error occurred while starting Roblox” message. In this article, we will explore this issue in-depth and provide you with effective solutions to resolve it.

Roblox is a popular online platform and game creation system that allows users to program games and play games created by other users. Unfortunately, like any other software, Roblox can also run into errors and glitches.

The “An error occurred while starting Roblox” error typically appears when the game client cannot connect to the game server, indicating that there might be an issue with your internet connection, software conflicts, or the Roblox servers themselves.

There are several reasons why “An error occurred while starting Roblox” might show up when launching the game – here are a few examples:

  • Internet Connection Issues: The most common cause of this error is a problem with the user's internet connection. Check to make sure that your connection is stable and functioning. Troubleshooting your network might help you resolve the issue.
  • Firewall or Antivirus Interference: Your firewall or antivirus software may sometimes block Roblox from accessing the internet. Try disabling these temporarily to see if they're causing the problem. If this resolves the issue, you may need to add Roblox to the list of exceptions in your antivirus or firewall settings.
  • Roblox Server Issues: If the issue isn't with your own system or internet connection, it's possible that the Roblox servers themselves are experiencing problems. You can check the Roblox status page for any ongoing server issues.
  • Outdated Roblox or Browser Version: An outdated Roblox player or web browser can also cause this issue. Ensure that you're using the latest version of your browser and that your Roblox player is updated.
  • Corrupt Roblox Installation: If none of the above solutions work, your Roblox installation may be corrupt. Uninstalling and then reinstalling the game can often fix this problem.

Fix 3. Disable your third-party antivirus

Third-party antivirus software is designed to monitor and block potentially harmful activities on your computer. While this is generally a good thing, these programs can sometimes mistake harmless activities, like running a game like Roblox, as threats.

In other words, the antivirus might be generating a false positive. When this happens, the antivirus software can prevent the game from starting or functioning correctly, leading to errors such as “An error occurred while starting Roblox.”

Disabling the antivirus software temporarily can help determine if it's the cause of the problem. If the game runs correctly with the antivirus software disabled, it's a good indication that the software was blocking the game. To resolve this, you can add Roblox as an exception in your antivirus software settings, so it no longer blocks the game, and you can still benefit from the protection the software provides.

Fix 4. Allow Roblox through Firewall

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
