Roblox installer stuck at 90%, "Checking for Updates," or "Configuring Roblox"? This is one of the most common Roblox issues. Here's the proven fix that works for 90% of users.
Roblox installation can get stuck for several reasons: leftover files from previous installations, antivirus software blocking the download, corrupted temporary files, or permission issues. The installer often freezes at specific points like 90% or during the "Configuring Roblox" phase.
This issue is especially common after Roblox updates or when reinstalling after a previous failed attempt. Windows 10 and Windows 11 users are equally affected. The fix below resolves the issue for approximately 90% of users.
Quick Tip: If you've been waiting more than 10 minutes on any installation step, the installer is likely stuck. Follow the steps below.
If Roblox is stuck on installing at 90%, the installation files are likely corrupted or being blocked by antivirus software. This specific percentage is where the installer verifies and configures game files, making it a common failure point.
Some users experience an infinite install loop where Roblox keeps reinstalling every time they try to launch a game. This happens when the protocol handler registration fails, causing the browser to trigger a fresh download on each play attempt.
The "Checking for Updates" freeze is related to the same underlying issue—leftover files from previous installations conflict with the new install process, preventing the installer from completing its final verification steps.
First, completely close any running Roblox processes that might be interfering with the new installation.
1. Press Ctrl + Shift + Esc to open Task Manager
2. Look for any processes containing "Roblox"
3. Right-click each one and select "End task"
4. Also end any "RobloxPlayerInstaller" processes
Remove all existing Roblox files to ensure a clean installation. This is the most important step.
1. Press Win + R
2. Type: %localappdata% and press Enter
3. Find and delete the entire Roblox folder
4. If deletion fails, make sure all Roblox processes are ended (Step 1)
Corrupted temp files can interfere with installation. Clear them out.
1. Press Win + R
2. Type: %temp% and press Enter
3. Press Ctrl + A to select all
4. Press Delete (skip any files in use)
5. Empty the Recycle Bin
Antivirus software often blocks Roblox installation. Disable it temporarily during installation.
1. Find your antivirus icon in the system tray
2. Right-click and disable real-time protection
3. For Windows Defender:
Settings > Privacy & Security > Windows Security
Virus & threat protection > Turn off Real-time protection

Download a fresh installer and run it with administrator privileges.
1. Go to roblox.com
2. Click "Play" on any game to download the installer
3. Don't run it yet! Find the downloaded file (usually Downloads folder)
4. Right-click RobloxPlayerInstaller.exe
5. Select "Run as administrator"
If the issue persists, use Revo Uninstaller to completely remove all Roblox traces before reinstalling.
1. Download Revo Uninstaller (free version works)
2. Scan for Roblox and remove it with "Advanced" scan
3. Delete all found registry entries and leftover files
4. Restart computer and reinstall Roblox
