If you've been searching for a roblox error code 264 same account launched fix, you're likely staring at that annoying grey box right now instead of playing your favorite game. It's a total mood killer when you're right in the middle of a session, or trying to join one, and the platform basically tells you that you're already busy somewhere else. The message usually says something along the lines of "Disconnected Same account launched from different device," which sounds a bit spooky if you know for a fact you're only sitting at one computer.
Don't panic, though. This doesn't necessarily mean you've been hacked, though we'll definitely check on that just to be safe. Most of the time, it's just a glitch in how Roblox tracks your active sessions, or maybe you forgot you left the app open on your phone in the other room. Let's walk through how to get this sorted so you can get back to your games without any more interruptions.
Why Does This Error Even Happen?
Before we jump into the actual fixes, it helps to understand what's going on behind the scenes. Roblox has a strict rule: one account, one session. You can't be playing Adopt Me! on your iPad while simultaneously trying to run a tycoon on your PC using the same login. When the servers see a second login attempt while one is already "active," it kills the connection for the first one and throws up Error 264.
Sometimes, the server is just slow. You might have closed the game on your phone five minutes ago, but the Roblox servers haven't "realized" you left yet. It's hanging onto that old session like a ghost. Other times, it's a caching issue where your browser or the app itself thinks you're still logged in because of some old data stuck in a temporary folder.
The Easiest Roblox Error Code 264 Same Account Launched Fix
The first thing you should do—and I know this sounds obvious—is log out of every single device you own that has Roblox on it. I'm talking about your phone, your tablet, your sibling's laptop, and even your Xbox if you've got it linked.
If you want to be thorough and do it all at once, there's a "nuclear option" in the settings that works like a charm.
- Log into your account on the Roblox website using a browser.
- Click the gear icon in the top right and go to Settings.
- Head over to the Security tab.
- Scroll all the way to the bottom until you see a button that says "Sign Out of All Other Sessions."
- Click that, confirm it, and then try launching your game again.
This is usually the most effective roblox error code 264 same account launched fix because it forces the servers to drop any "ghost" sessions that might be lingering. It's like a fresh start for your account's connectivity.
Clearing the Roblox Cache on Windows
If the "sign out" trick didn't work, the problem might be living on your computer's hard drive. Windows likes to store temporary files to make apps load faster, but sometimes these files get corrupted. When Roblox tries to launch, it sees this old, "dirty" data and gets confused, thinking you're already in a game.
Clearing the cache sounds technical, but it's actually pretty simple. Here's how you do it:
First, make sure the Roblox app is completely closed. Check your system tray (the little icons by the clock) to ensure it's not running in the background. Then, press the Windows Key + R on your keyboard to open the "Run" box. Type in %temp%\Roblox and hit Enter.
A folder will pop up filled with a bunch of weirdly named files and folders. Don't worry; none of this is your actual game data or your account info. It's just junk. Select everything in that folder and hit Delete. If a window pops up saying a file is in use, just hit "Skip." Once that's done, try opening Roblox again. You'd be surprised how often this clears up weird errors.
Dealing with Browser Issues
If you play Roblox through a web browser rather than the standalone Windows app, your browser's cookies might be the culprit. Sometimes Chrome or Edge holds onto a "session cookie" that tells Roblox you're still logged in even after you've closed the tab.
A quick way to test this is to try joining a game in Incognito Mode or Private Browsing. If the game works fine there, then you know it's a browser cookie problem. To fix it for real, you'll need to clear your browser's cache and cookies. Just keep in mind that doing this will probably log you out of other websites too, so make sure you know your passwords before you hit that "clear data" button.
Checking Your Account Security
I hate to bring it up, but we have to talk about the possibility that someone else is actually on your account. If you've tried the roblox error code 264 same account launched fix methods above and the error keeps coming back immediately, it's time to look at your security.
Go back to your Security settings on the Roblox site. If you don't have Two-Step Verification (2FA) turned on, do it right now. Use an authenticator app if you can, as it's way more secure than email codes. Also, change your password to something completely new—not just "Password123" with an extra number at the end.
If someone was logging into your account from another location, changing your password and signing out of all sessions will boot them off and keep them off. It's better to be safe than sorry, especially if you've spent a lot of Robux on your avatar.
What if the Error Persists on Mobile?
If you're getting this on a phone or tablet, the steps are slightly different. Apps on mobile devices are notorious for staying "active" in the background to save your spot.
On an iPhone or Android, try force-closing the app. Don't just swipe to the home screen; actually bring up the app switcher and swipe Roblox away so it fully shuts down. If that doesn't help, you can try offloading the app or clearing the app data in your phone's settings. As a last resort, just delete the app and reinstall it from the App Store or Play Store. It's a bit of a pain, but it refreshes all the local files that might be causing the 264 error.
A Note on Using Multiple Windows
Some players like to use "multi-instance" managers to run two Roblox accounts at once. If you're doing this, Error 264 is basically an occupational hazard. If you accidentally try to open the same account in two different windows, the system will catch you every time. Double-check that your multi-instance tool is actually logging into different accounts for each window. If you're just a regular player, make sure you aren't accidentally double-clicking the "Play" button or opening two browser tabs for the same game, as that can occasionally trigger a false positive for this error.
Final Thoughts
Usually, a roblox error code 264 same account launched fix is just a matter of logging out and logging back in. It's one of those "turn it off and on again" situations that actually works. Whether it's a ghost session on the server or a bit of corrupted cache on your PC, it's rarely a permanent problem.
Just remember to keep your account secure with 2FA so you don't have to wonder if the "same account launched" message is a hacker or just a glitch. Once you've cleared out those old sessions and wiped your cache, you should be back to gaming in no time. If you've done everything and it's still acting up, give it about an hour. Sometimes the Roblox servers just need a little time to realize you've actually left the building. Happy gaming!
