Roblox is a popular online game creation platform where players can enjoy thousands of games created by other users and build their own games as well. Roblox is quite easy to run with minimal system requirements making it accessible to anyone with a decent computer. 

However, if you’re having difficulty launching Roblox, there’s definitely something wrong.

Usually, the ‘an error occurred while starting Roblox’ message occurs when the platform can’t find some files on your system. Other factors such as improper settings, third-party applications, and outdated software could also trigger this error message. 

Today, we will show you what to do if you see the ‘an error occurred while starting Roblox’ message on your computer.

1. Restart Your Computer. 

If Roblox won’t launch on your computer, the first thing we suggest doing is restarting your system. Roblox’s installation files may not have initialized properly when you first boot your system, causing it to run into errors.

Follow the steps below to launch Roblox as an admin:

Since Roblox is an online platform, it needs a decent internet connection to run. If the platform encounters an error at launch, it may indicate that your network is unstable or slow. You can confirm this by running a speed test using

If the result shows that your network is the problem, restart your router to refresh your connection. Remove your router from the power source and allow it to rest for a few seconds. Plug back in your router’s power cable afterward to restart it.

After flushing your DNS, restart your computer and try launching Roblox again. 

5. Allow Roblox Through Your Firewall. 

Windows Defender Firewall is a security feature on your operating system that manages the access of applications to the internet. If Roblox doesn’t launch on your computer, your firewall may be blocking it from accessing your network.

6. Disable Your Antivirus. 

If you’re using third-party antivirus, disable it first before launching Roblox. Some antivirus software gets too protective and flags down even legitimate applications, restricting their access to your system and network. 

You can also add Roblox to your antivirus’ safelist or allowed list if it supports that feature to prevent the program from blocking the platform. 

7. Update Windows. 

The current version of Windows you’re using may not be compatible with the version of Roblox installed on your system. To rule out this scenario, ensure that you’re using the latest version of Windows on your computer. 

For Roblox, you don’t have to worry since the game updates itself every time you launch it. 

See the steps below to update Windows: 

  1. On your keyboard, press the Windows + I keys to access Windows Settings
  2. After that, click on Update & Security
  3. Finally, go to Windows Update and click on Check for Updates
