Facing errors, crashes, and other similar problems while playing Roblox is not an uncommon experience. This isn’t because the platform isn’t correctly built but because of its enormous complexity.

In this specific guide, we’ll help you solve Roblox error 6, one that occurs when Roblox’s launcher fails to start the game properly.
If you’ve been dealing with this recently, now’s the right time to learn how to fix it. Let’s get into it.

The Problem Explained
This error isn’t as common as some of the other Roblox errors, and although that’s a good thing, it’s also a downside at the same time, as there aren’t many solutions available.
However, we do know that the Roblox Error Code 6 occurs when the launcher is unable to start the game properly, either due to a sudden loss of internet connection or an issue related to the lack of administrator rights.
There can be a few other causes as well, although slightly less common. This could be an antivirus software blocking access to the game or a compatibility issue.
When it comes to the error panel itself, it doesn’t explain much and leaves users confused, without a potential clue about what the problem could be.
We’ve also seen users reporting two different error panel messages about Error Code 6, though both are pretty vague and don’t contain much valuable info.
Thankfully, we know about multiple effective fixes for this problem, and we’ve prepared step-by-step guides for all of them in the sections below. Follow them to fix this problem and get back to playing.
Fix 1: Ensure No Other Roblox Instances Are Running
One of the main things that make Roblox unable to launch is the game not being fully closed and one or more instances of it running in the background while you’re trying to launch it anew.
This can happen in multiple scenarios, such as a slower computer not fully quitting the game before the user attempts to relaunch it or a background process being stuck due to a bug or an error causing the system to think that the game is still running.
The best way to ensure this isn’t happening is by following the steps below:
- Right-click your Windows taskbar and choose Task Manager from the list of options.
- Open the Processes section and search for anything related to Roblox.
- Choose all Roblox-related processes and right-click them, then choose End Task.
Upon ending all the Roblox processes, try starting the game once again. It should now launch properly if the problem was caused by multiple instances running on your PC.
If it’s simpler for you, you can get the same outcome by restarting your computer, as that would automatically stop all Roblox instances and processes as well.
We also recommend logging out of your account from any other place you may be logged in from, such as multiple browsers or another computer. If you have automatic login enabled, the game may not be launching because Roblox’s servers detect another instance already running with your account and therefore block the access.
Fix 2: Run Roblox As An Administrator
Some users reported that running the game with administrator privileges was the solution for the Roblox Error Code 6.
This fix is easy to apply and takes just a few clicks, but if you don’t know how to do it, take a look at the steps below as we explain everything in detail.
- Right-click the Roblox shortcut that you are using to launch the game, then choose Run as Administrator.
- The game will launch with full administrator privileges if your windows user is allowed to do so.
This should solve the problem, and if it does, you most likely wouldn’t want to have to do this every time you launch the game, which is why we recommend doing the following:
- Right-click the Roblox shortcut, just like you did in the previous steps, and then choose Properties. Click Compatibility in the top-bar menu within the window that opened.
- Then, “tick” the “Run this program as an administrator” option, and click Apply then OK within the same window to confirm and save the changes, as shown in the image below.
Now the game will always run with administrator privileges when you launch it, which should prevent the Roblox Error 6 from appearing.
Multiple users reported this as a working fix, and hopefully, it should help you as well.
Fix 3: Enable Compatibility Mode
Sometimes the Roblox Error Code 6 issue appears when there are compatibility issues with the game. The reason the launcher cannot start the game could be because of the user not launching it in compatibility mode, which you’ll solve by enabling Windows Compatibility mode.
Here’s how to do that:
- Right-click the shortcut you’re using to launch Roblox, and then choose Properties.
- Navigate to the Compatibility tab by clicking it in the top-bar menu within the properties window.
- Within the compatibility section, tick the “Run this program in compatibility mode for:” option and choose the right operating system.
- Click Apply and then OK to save the changes.
Now you can launch the game without seeing the Roblox Error Code 6.
Fix 4: Add Roblox As A Firewall & Antivirus Exception
If your firewall misidentifies Roblox as a potentially hazardous application, it could obstruct your connection to the authentication server, and you won’t be able to commence the game.
To avoid this, we suggest including Roblox in your firewall’s exclusion list.
Follow the steps below to do this easily:
- Press Windows + S on your keyboard simultaneously to open the Windows search panel. Then, type in Firewall & Network Protection, and press Enter on your keyboard to initiate the search.
- Scroll down the panel and click Allow an App Through The Firewall, as shown in the image below.
- Add the Roblox executable file as an exception, which should ensure that the connection won’t be blocked by the firewall anymore.
You can also add Roblox to the list of trusted apps within your antivirus settings, though we can’t provide the right steps for this method since different users have different antivirus programs installed.
Now you can try relaunching Roblox, and this time it should work if the problem was caused by your firewall blocking access.
Fix 5: Power Cycle Your Router
Last but not least, we recommend power cycling your router when experiencing the Roblox Error Code 6, as some users reported that a potential connection issue might be causing the launcher to fail.
This is logical as having an unsteady link or no link at all means not being able to connect to the Roblox confirmation server, thus, the game doesn’t start.
To power cycle your router, follow the steps below:
- Locate the power button on your device and switch it off.
- Wait about five minutes. You can restart your computer while waiting.
- After five minutes pass, switch the power back on and wait until the connection is restored.
Now you can try launching Roblox and see if the error persists. The game should launch correctly, as users reported.
So, you have learned about the Roblox Error Code 6 and how to deal with it.
It’s a vague problem without much explanation provided in the error panel, but you should be able to fix it by applying the fixes listed in the guide above.
