Roblox Installer Stuck at 90% (Windows 10/11 Fix)
You download Roblox, run the installer, and… it gets stuck around 90% forever.
This issue is usually caused by:
- Leftover Roblox files from previous installs.
- Antivirus or firewall blocking the installer.
- Broken Windows temp or network settings.
Let's fix it step by step.
1. Cancel the Install and Close All Roblox Processes
- Close the installer window.
- Open Task Manager (
Ctrl + Shift + Esc). - End any process named:
- RobloxPlayerInstaller
- RobloxPlayerLauncher
- Roblox
2. Clean Temporary Roblox Files
- Press
Win + R→ type:
%localappdata%\Roblox
- Delete the entire Roblox folder.
- Open
C:\Users\<YourName>\AppData\Local\Tempand delete any Roblox-related files. - Empty Recycle Bin.
3. Reset Network Components
The installer needs to download additional files. If your network stack is corrupted, it can hang at 90%.
- Open Command Prompt (Admin).
- Run:
ipconfig /flushdns
netsh int ip reset
netsh winsock reset
- Restart your PC.
4. Temporarily Disable Antivirus / Firewall
Third-party antivirus can silently block Roblox downloads.
- Disable real-time protection in your AV software.
- Keep Windows Defender Firewall on, but turn off overly strict modes.
- Try the installer again.
After the install finishes, you can re-enable everything and add Roblox to the allow-list.
5. Use the Launcher Instead of Old Installers
- Go to:
%localappdata%\Roblox\Versions
- Open the newest folder (long ID name).
- Right-click RobloxPlayerLauncher.exe → Run as administrator.
If there is no Versions folder at all, download a brand-new installer from the official site — not from old backups or copies on USB drives.
