How to Fix Roblox Not Launching [Causes & Fixes]

How to Fix Roblox Not Launching: Troubleshooting Methods

The first troubleshooting way to fix this issue is to restart the PC. In most cases, this simple step helps Roblox launch successfully. If the Roblox Player still is not launching, then apply these troubleshooting techniques one by one until you come out of the situation.

Check Roblox Server Status

RobloxPlayer may not launch if the server is down for scheduled maintenance. You can check the server status by reaching out to Roblox’s support team or checking their social media for updates. You can also check the Roblox Discord to see if other users are facing the same issue.

Check Your Browser

Sometimes on the official site of Roblox, a pop-up doesn’t appear through which we launch Roblox. So you can use a different browser or clear the browser cache and cookies, and then try again. Mostly, the pop-up appears simply with this step. However, if it’s still creating a problem, then you have to reset your internet settings. Just follow these steps:

• Press Windows + S and type ‘Internet Options’ in the search bar.
• Click ‘Internet Options’ to open the Internet properties window.
• Hit the ‘Advanced’ tab and click ‘Reset.’

• You will see the ‘Security’ tab, click it, then select the ‘Trusted Sites’ icon.
• Hit ‘Sites,’ then add ‘http://www.roblox.com‘ and click ‘Add.’

• Now click ‘Close’ to finish, then close the window.

Restart your browser and try launching Roblox again.

Run Roblox As Admin

Are you still in a bind because the Roblox is not launching? If you have already been running Roblox as an administrator, quit this step. Otherwise, run it as an administrator. Here, you have to go all the way:

• Right-click on the Roblox shortcut.
• Select Properties.
• Go to the Compatibility tab.
• Check the box for Run this program as an administrator.
• Click Apply, then OK.

This might help resolve your issue.

Delete Temporary Internet Files & Cookies

Temporary files are deleted by opening the run box after pressing Windows + R.
To open the folder where temporary files are saved, you will type %temp% and press Enter.
Press Ctrl + A to select all files. Then press Delete. This will delete all temporary files except those that are in use.

Here’s how you can delete cookies in Google Chrome:

• Open Chrome.
• Click the three dots in the upper-right corner.
• Go to More tools > Clear browsing data.

• Check all the boxes (Browsing history, Cookies, and Cached images/files).
• Under Time range, select All time.
• Click Clear data.

Once finished, close the window and try launching Roblox again.

Delete the Roblox AppData Folder

The Roblox AppData folder may interfere with the launching of the Roblox Player, so you can try launching it by deleting the Roblox AppData folder.

• For this, you will open the file explorer by pressing Windows + E.
• Now you will go to this location: C:\Users\yourusername\AppData\Local, and here you will replace the default username with your actual username and press Enter.
• By right-clicking on the Roblox folder, the delete option will appear. Hit this option.

Disable Proxy

Another reason the game might not work is if you are using a proxy server. To fix this, try disabling the proxy settings:

• In the Windows search bar, type Proxy and click on Change proxy settings.
• Toggle off both Use a setup script and Use a proxy server.

Disable Proxy For Your LAN

• Open the internet options by pressing Windows + S
• Once the options are open, you will go to the Connections tab.
• Hit LAN settings.
• Move the cursor to the Proxy settings where you will uncheck Use a proxy server for your LAN.

Ensure Roblox is Allowed To Run

To ensure that Roblox is allowed to run in Chrome

• When we open the game, a message box appears saying “External Protocol Request”.
• Here we have to tick the box that says Remember my choice for all links of this type and then we will click Launch Application.
• If we click Do Nothing before then we will have to reinstall Roblox and follow these steps again.
• If it still doesn’t work, try updating Chrome or using a different browser.

Update Windows & Roblox

If there’s a problem with the Roblox app, try updating it through our website. If that doesn’t work, update Windows:

• Press Windows + I to open Settings.
• Go to Update & Security > Windows Update.

• Click Check for updates and, if any are available, Download & install them.

After updating Windows, try opening Roblox again.

The System Time and Date Should Be Correct

Right-click on the system tray (where the date and time are displayed) and select Adjust date/time.

In the Date and Time settings, make sure the time zone is correct and that the Set time automatically is turned on.

Change Graphics Level

To improve Roblox performance, try lowering the graphics settings from the game menu. If Graphics Mode is set to Automatic, switch it to Manual first to adjust the settings yourself. You can also change graphics settings from the Roblox studio.

• Go to Tools > Settings and select Rendering.
• Find QualityLevel and set the graphics level manually.

Lowering the graphics level may reduce image quality but can help Roblox run smoother.

Disable Browser Plugins

Sometimes, browser plugins like AdBlock can stop Roblox from working correctly. This can be fixed by disabling these plugins.

• Click the three dots in the top-right corner of Chrome.
• Go to Extensions.

• Turn off extensions by switching each toggle from right to left.

After disabling the extensions, restart Chrome and try opening Roblox again.

Update Graphics Card

Sometimes, an outdated graphics card driver can prevent Roblox from working. You can fix this problem by updating the graphic driver after downloading and installing the latest driver for your model from the trustworthy graphics card manufacturer’s website.

The other way is to update through Device Manager:

• Choose Device Manager by pressing Windows + X.
• Double-click Display Adapters.
• You will right-click on your graphics card and select Update Driver.
• Follow the instructions to complete the update.

After updating, restart your computer to see if the problem is fixed. You can also install a software to keep your graphics card driver up-to-date without manually doing it.

Temporarily Disable Antivirus/ Firewall

It’s very usual that antivirus or firewalls block the downloading of software and show a false positive. You can disable them before downloading and then activate them again once the download is complete. Another way is to add that particular software, like Roblox, to the exception list so they won’t block it from launching in the future.

• Type Firewall in the Windows search bar and click on the top result.
• Select Allow an app or feature through Windows Firewall.

• Find Roblox in the list and make sure it’s checked as an exception.
• Similarly, add Roblox as an exception in your antivirus software. (For detailed instructions, you can contact your antivirus support team.)

• Additionally, ensure that the ports UDP 49152 – 65535 are open on your PC. If they are blocked, Roblox won’t be able to run.

Run SFC Scan

Corrupted or missing registry keys can sometimes prevent Roblox from starting. You can save your side by cleaning the registry with the Registry Cleaner tool.

Moreover, to fix the corrupt system files you can run a SFC scan:

• For this open Command Prompt as an administrator
• Then type sfc /scannow and press Enter.

After completing the scan, restart your computer to replace any corrupted files during the reboot.

Disable the Discord Game Overlay

Disabling Discord’s in-game overlay may improve stability by preventing potential conflicts. Here’s how:

• Launch the Discord app.
• Go to User Settings by clicking the gear icon next to your username shown at the bottom left.
• In the left pane, move the cursor down to the Registered Games section under Activity Settings.
• Disable the Overlay for Roblox after finding Roblox in the list of registered games. Click the monitor icon next to it to turn off the overlay.

Disabling the overlay specifically for Roblox will prevent potential conflicts, reducing the chances of crashes during gameplay.

Change the DNS Server Address

If Roblox is not launching due to a network issue, changing your DNS server might help. Here’s how to do it:

• Open the Run window: Press Windows + R on your keyboard.
• Enter network settings: Type ncpa.cpl and hit Enter.
• Access network properties: Right-click your active network (like Wi-Fi or Ethernet) and select Properties.
• Choose IPv4 settings: Find and select Internet Protocol Version 4 (TCP/IPv4), then click Properties.

• Enter new DNS addresses: Choose “Use the following DNS server addresses”.
• For the Preferred DNS server, type 1.1.1.1 or 8.8.8.8. For the Alternate DNS server, type 1.0.0.1 or 8.8.4.4.
• Save and restart: Click OK to save, then restart your computer to apply the changes.

Flush DNS

To help fix network issues that might be affecting Roblox, you can clear the DNS cache. Here’s how:

• Open Command Prompt as Administrator by typing “cmd” in the Windows search bar, right-click Command Prompt and tick Run as administrator.
• Clear the DNS cache by moving to the Command Prompt, type ipconfig /flushdns and press Enter.

• Restart your PC: After clearing the cache, restart your computer to apply the changes.

This can help refresh your network connection and might resolve the problem with Roblox.

Reinstall The Roblox Desktop App

If Roblox is still not launching, reinstalling the app might help. Here’s how:

Uninstall Roblox:

• Close all apps: Make sure Roblox and any other open apps are closed.
• Go to Add or Remove Programs: Press Windows + S, type Add or Remove programs, and select it.
• Uninstall Roblox: Find Roblox in the list, choose it, and select Uninstall. Confirm when prompted.

Delete the Roblox Folder:

• Open File Explorer: Press Windows + E.
• Go to the AppData folder: Navigate to C:\Users\yourusername\AppData\Local\ (replace yourusername with your account name).
• Delete the Roblox folder: Find the Roblox folder, select it, and press Delete.

Reinstall Roblox:

• Go to the official Roblox site.
• Log in and choose a game: Sign in, select a game, and click Play.
• Download Roblox: The Roblox app will download and install automatically.

You should now be able to play Roblox! If you still have issues, feel free to ask for more help.
