Fixing VS Code Error: "Failed to create file handle: The process cannot access the file because it is being used by another process"

Method 1: Force Kill Everything via Command Prompt

Sometimes Task Manager misses nested background processes. Let's use taskkill to force-terminate anything related to the IDE.

1. Click Cancel on that error box for a moment to close the hung installer loop.

2. Press the Windows Key, type cmd, right-click Command Prompt, and select Run as administrator.

3. Copy and paste the following commands one by one, hitting Enter after each:

   Commands:

   taskkill /f /im code.exe
   taskkill /f /im antigravity*
   

4. Now, find your installer file, right-click it, and choose Run as administrator to try again.

Method 2: Use an Invalidation Rename (The Quick Bypass)

If a process still has a hidden lock on chrome_100_percent.pak, we can trick Windows by breaking the path it's holding onto.

1. Press Win + R, type %localappdata%\Programs, and press Enter.

2. Open the Antigravity IDE folder.

3. Look for chrome_100_percent.pak.

4. Right-click and rename it to something like chrome_100_percent.pak.old.

   • If it lets you rename it: The lock is bypassed. Run the installer again.

   • If it says "File in Use": Go to Method 3.

Method 3: The Nuclear Option (Safe Mode)

If a stubborn system service or background antivirus driver is locking it up, booting into Safe Mode will prevent it from starting up, leaving the file completely free to be modified or deleted.

1. Hold down the Shift key on your keyboard while clicking Restart in your Windows Start Menu.

2. Your PC will reboot into a blue screen. Go to: Troubleshoot > Advanced options > Startup Settings > Restart.

3. Upon reboot, press 4 or F4 to enable Safe Mode.

4. Once you are logged into Safe Mode, navigate back to %localappdata%\Programs and completely delete the Antigravity IDE folder.

5. Restart your computer normally and run the installation clean.
