[Bug]: Installation fails on Windows due to Long Path issue (Failed to create file handle)

Description:
Hi team, I am unable to install the application on Windows using the default installation path. The setup fails during the file extraction process when it reaches a deeply nested node_modules directory related to @react-native.

The error message incorrectly suggests that Visual Studio Code is running, but I have verified via Task Manager that no VS Code processes are active. The issue seems to be that the 32-bit installer does not support or respect the Windows Long Paths feature.

Error Message:

codeText

There was an error while Opening file handle:
"C:\Users\Admin\AppData\Local\Programs\Antigravity\node_modules\@react-native\community-cli-plugin\node_modules\@react-native\debugger-frontend\dist\third-party\front_end\models\issues_manager\descriptions\arNavigationRegistrationWithoutTransientUserActivation.md":

Failed to create file handle: The system cannot find the path specified.

Please verify there are no Visual Studio Code processes still executing.

Steps to Reproduce:

  1. Update using “Restart to Update“ button.

  2. Keep the default destination path (C:\Users\[Username]\AppData\Local\Programs\Antigravity\).

  3. The installation halts with the error mentioned above.

Troubleshooting Steps I’ve Already Taken:

  • Checked Task Manager: Verified that absolutely zero code.exe or Visual Studio Code processes were running in the background.

  • Enabled Windows Long Paths: I manually enabled LongPathsEnabled = 1 in the Registry (HKLM\SYSTEM\CurrentControlSet\Control\FileSystem), via PowerShell, and restarted my PC. The installer still throws the exact same error.

  • Run as Administrator: Attempted to run the setup as Admin, but the result is the same.

Environment:

  • OS: Windows 11

  • Antigravity Version: 1.19.6
    VSCode OSS Version: 1.107.0 (user setup)

Additional Context:
Because the path length exceeds the standard 260-character limit of Windows, and the installer itself (being 32-bit or built with an older setup compiler) doesn’t seem to have long path awareness manifested, it fails.
