How to Fix Antigravity Not Working on Windows 11

Antigravity (often referring to Antigravity AI IDE, the Antigravity runtime engine, or the Antigravity launcher) is an impressive AI-powered development environment — but as with any modern tool relying on multiple dependencies, background services, and GPU/CPU resources, things can occasionally stop working. Whether the IDE isn’t launching, keeps crashing, won’t install updates, or fails to load AI models, you’re not alone. Many Windows 11 users face similar issues due to software conflicts, missing runtimes, or corrupted configuration files.

If you’re here reading this guide, you’re probably trying to resolve Antigravity issues on your Windows 11 PC. The good news? Most problems can be fixed with a few targeted troubleshooting steps.

In this in-depth guide, we walk you through all the effective ways to fix Antigravity not working on Windows 11, complete with explanations and step-by-step instructions.

Why Antigravity Might Not Be Working on Windows 11

Before jumping into fixes, here are the most common causes:

• Missing or outdated dependencies (like .NET Runtime, Python, Node.js)
• Corrupted Antigravity installation files
• Damaged configuration or workspace folders
• Antivirus or firewall blocking AI libraries
• GPU driver issues
• Insufficient permissions
• Conflicts with VS Code, JetBrains, or other IDEs
• Windows updates interfering with runtimes

Now that we understand the causes, let’s move to the solutions.

1. Restart Your PC and Relaunch Antigravity (Simple but Effective)

A simple restart resets locked files, background processes, and stuck runtime services.

1. Click Start → Power → Restart.
2. After rebooting, launch Antigravity again.

If the IDE opens normally afterward, the issue was temporary.

2. Run Antigravity as Administrator

Antigravity may require elevated permissions for GPU access, model loading, extensions, or environment setup.

1. Right-click the Antigravity icon.
2. Select Run as administrator.
3. Click Yes on the UAC prompt.

If the app runs only in admin mode, you may need to adjust permissions later (Fix #10).

3. Update Required Dependencies (.NET, Python, Node.js, C++ Runtime)

Antigravity relies on major runtimes. If these are missing or outdated, the IDE may not launch.

Install/update the following:

.NET Desktop Runtime: Download from Microsoft: https://dotnet.microsoft.com/download

Python 3.x: Install from https://www.python.org

Node.js LTS: Install from https://nodejs.org

Microsoft Visual C++ Redistributables:Install both x64 and x86 versions.

1. Install or update each runtime.
2. Restart your PC.
3. Launch Antigravity again.

4. Update Your GPU Drivers (Important for AI Features)

Since Antigravity’s AI engine may use your GPU for model acceleration, outdated GPU drivers can cause crashes or startup failures.

NVIDIA:

• Open GeForce Experience → Drivers → Update
• Or install from NVIDIA’s site

AMD:

• Open Adrenalin Software → Check for updates

Intel:

• Install from Intel Driver & Support Assistant

Restart your PC afterward.

5. Disable Antivirus or Firewall Temporarily

Some antivirus tools (especially Avast, Bitdefender, McAfee, Kaspersky) falsely flag AI libraries or Python executables.

1. Temporarily turn off real-time protection.
2. Add Antigravity folders to antivirus exclusions:
   • C:\Program Files\AntigravityAI
   • %LOCALAPPDATA%\Antigravity
3. Relaunch Antigravity.

If Antigravity starts working, whitelist it in your antivirus settings.

6. Repair or Reset Antigravity Installation

Windows can repair an app when it becomes corrupted.

1. Open Settings → Apps → Installed apps.
2. Search for Antigravity.
3. Click Advanced options.
4. Select Repair.

If that doesn’t work:

5. Select Reset (this resets settings but keeps your files).

Open the app again after repair/reset.

7. Delete Corrupted Cache or Configuration Files

Sometimes the IDE’s configuration gets damaged, causing the app to freeze or fail to load.

1. Press Windows + R.
2. Type:

%LOCALAPPDATA%\Antigravity

3. Delete:
   • Cache
   • Temp
   • Config (only if necessary)

Restart Antigravity.

8. Reinstall Antigravity Completely

If none of the above worked, a clean reinstall usually fixes everything.

Uninstall:

1. Open Settings → Apps → Installed apps.
2. Select Uninstall for Antigravity.

Delete leftovers:

1. Remove any leftover folders in:
   • C:\Program Files\AntigravityAI
   • %LOCALAPPDATA%\Antigravity

Reinstall:

1. Download the latest installer from the official site.
2. Install Antigravity again.

Launch and test.

9. Disable Conflicting Background Apps

Some apps interfere with developer tools and AI runtimes:

• VS Code auto-run extensions
• JetBrains Toolbox
• Docker Desktop
• WSL background processes
• Python virtual environment managers
• Node.js watchers
• Nvidia GeForce overlay
• Discord overlay

1. Press Ctrl + Shift + Esc (Task Manager).
2. Open the Startup apps tab.
3. Disable unnecessary background apps.
4. Restart your PC.

Try launching Antigravity again.

10. Fix Permissions on Antigravity Installation Folder

If your account doesn’t have proper access, Antigravity might not load its executables.

1. Navigate to:

C:\Program Files\AntigravityAI

2. Right-click the folder → Properties.
3. Go to Security tab.
4. Ensure your user account has:
   • Read & execute
   • Modify
   • Write

If not, click Edit → add permissions.

11. Check for Windows Updates (Required for New Runtimes)

Antigravity may require recent Windows 11 components.

1. Go to Settings → Windows Update.
2. Click Check for updates.
3. Install all available updates.

Then reboot your PC.

12. Clean Boot Windows 11 to Check for Software Conflicts

A clean boot loads only essential Windows services.

1. Press Windows + R.
2. Type msconfig → Enter.
3. Go to the Services tab.
4. Check Hide all Microsoft services.
5. Click Disable all.
6. Go to Startup apps in Task Manager → Disable all.
7. Restart your PC.

If Antigravity works now, another app was causing the conflict.

Wrapping Up

Antigravity not working on your Windows 11 PC can be frustrating, especially when you’re excited to dive into AI-powered development. But the good news is that most issues boil down to missing dependencies, corrupted configuration files, or system conflicts — all of which are easy to fix using the steps in this guide.
